So, I have build my preamp power supply. I'm using MIDI DIN connectors instead of the 4 pin connectors. It powers up, so that's a good sign. Both light bulbs still work. But I cant get the right output out of it yet.
Its a very low volume, distorted sound I'm getting so far. I don't know if its the preamp or my power supply box outputs. I have everything hooked up correctly, all pins are going to the right pins. I'm not sure where the output jacks sleeve terminals should go, since there is no where for them on the pin connector. I tried just putting them to ground but its still giving me this distorted low volume output. Its bearly even an output at all.
Please help? What am I missing here?

This isn't really a nice way to treat your piano, and it is not the best way to remove the rivet cleanly.  (The drill will do a clean job.)

Yeah, but the cool thing is, its not on the name rail it self, its on the chassis that holds the preamp circuit. But thanks for you're help! I figured out the other questions that I had by myself, so now I'm all set. Its amazing it still works and the bulbs are still operating. I cant wait to hear it. If anyone else has some advice on fixing up my preamp, it would be much appreciated, thanks :)

I am so excited, I'm making a power supply for the original preamp. But I need some help before I start.

First, I'm changing the 4 pin connector to a 5 pin (MIDI DIN style). How do I get the original off? It's not screwed on, its actually attached very difficultly to the chassis.
And second, I have the power supply. It's a 24V DC adapter. The specs call for 25 volts, but this measures out to be just fine. Will it work? And if it's too much can the preamp handle it?
And thirdly, I understand that the vibrato is powered by 2 lamps. Does anyone know what kind they are just in the case their broken?

Thanks a bunch, I'm so ready to get this thing powered up. This is way cheaper than buying stuff through vintage vibe or something.

Yeah, I made my own preamp circuit since the older one cant work without the bottom half or a power supply (maybe someday). (Oh, and I guess mine isn't much of a "preamp" if its passive, lol.)

It consists of two outputs, volume and tone pots, and an LED on/off indicator just for fun. I don't know what to do with that big jack sticking out of the input yet. It was going to be an XLR output, but I decided not to try it. If anyone has any ideas on what could go there, let me know. I want this thing to be different. ;)

I think it turned out really nice! I love the red with the red dice knobs. It was a pretty easy paint job, I just primed it in a good coating and then applied a special Krylon plastic spray paint. It couldn't get rid of the deep scratches on the top, but I guess its alright for now. I should have put something in those dings to smooth it out.
Over all, it looks a lot better than it did. All it needs is new key covers and new tolex and it'll look really pro :)

To answer your question though, there probably isnt a problem with your piano if it is stiff, thats just the way some of those early 70's Rhodes were.

Yeah, today I just tuned it and voiced it as well lifting up the escapement to help with the double striking and choking. It sounds a lot better now, and its nice being able to play it and not have to worry about the sound being too harsh and all over the place.
The keys still feel stiff, but I guess you're right, that's just the way they are. At least its still playable and sounds good. Thanks everyone for all your knowledge! :)

Wow Sean, thanks for the info. I'm pretty sure mine is from 1974. It does have half wood hammers, and I think its the mid 74' kind of keys you talked about. Everyone that's played it notices that you really have to apply pressure on the keys, and if you hit one just right it will double strike and choke out the note.
It certainly feels old, but my half broken 100 year old upright piano even feels way better. Even though its got many dead keys, it still feels a lot nicer to play.
I really want remedies to two main problems: Choked out notes or double striking, and key stiffness. If I can fix these problems without spending a bunch trying to replace everything, that would be great. ;)

The Mark V to me feels easier to press the notes than a cheapish midi keyboard - but I can only play with 80% of the speed.

Hard to describe.

My Mark I's keys feel very hard to me. Its not like one of my other keyboards where I can just glide on the keys, its totally different (trying to do that whole piano growl thing hurts like crap, lol).
One of my main problems is trying to figure out why if I hit a key too hard, the note chokes. I've tried adjusting the escapement countless times. And no matter what I do, these old keys wont loosen up to my playing ability. I played a CP70 a while back and it felt great and totally different. Is there a different playing technique when it comes to the Rhodes that I'm not aware of?

This is probably going to sound like a stupid question, but should the action of a Rhodes be different from a normal acoustic piano or other electric piano? I'm trying to figure out if I'm doing something wrong, my piano just doesn't feel right sometimes.

Parts, Service, Maintenance & Repairs / Rhodes to keyboard stand mod! :)
« on: September 30, 2010, 06:24:58 PM »
I have great news for anyone that has a Rhodes being used with a keyboard stand!
I have this kind of stand: At first I really didn't like how this stand was holding my Rhodes. It looked like it was sturdy, but when the Rhodes got bumped and slipped off the stand, I knew there was gonna be some problems. Now, Ive finally found a decent mod that makes it much more sturdier. Just mount the stand to the bottom of the Rhodes! On the bottom of the piano there are some little metal foots that screw into the wooden bottom, and on the stand I use there are little cutouts in the frame (I don't know why they are there but I thank God they're there).
Just unscrew the two back foots from the Rhodes and line up the stands cutouts with those two screw holes, then screw the foots back on with the stand frame in between the bottom of the piano and the foots so the stand frame is nice and snug and mounted permanently to the piano. It wont slip, and it will be almost as sturdy as the original Rhodes legs. I even have mine set up in the old "stand up position" right now! This minor mod helps so much. Try it out if you have a stand like this or something close to it! :)

Parts, Service, Maintenance & Repairs / Missing harp support shims?
« on: July 23, 2010, 01:32:25 PM »
Hey, my 88 key mk1 has 2 shims supporting the left side of the piano harp and only one thinner shim on the right side. Is that normal? It makes the harp look uneven as it sits on the rest of the keybed.
And the reason I'm concerned is because I think this might have something to do with the higher notes choking out because of the uneven escapement.

Gosh, I hate those stupid 4 pin/5 pin connector things they used. I took the control panel out of my suitcase mod, and just stuck some 1/4 inch outputs on it. Much easier to deal with. Sure I wish I could use the tone and vibrato the original control panel had, but without the bottom speaker part, its useless.

If you want to use those controls, you will need to figure out what pins do what, and find/make an adapter. one pin is +volts, another is -ground, the others are the stereo outputs. If you can figure out what pins are what, then you can make your own power supply and output to then power the preamp and get signal from the piano.
That's what I would do, and what I want to do sometime with mine ;)

Suggestion, this is probably what i would try....

Get a fairly thick piece of plywood, slightly smaller than the footprint of the rhodes. Mount it to the stand permanently,and cut a hole for the pedal rod. Paint it black ( optional) and mount some sort of non slip pads on it. The stand will still fold,and it should be sturdier.

Thats a really great idea! Thanks a bunch, I'm gonna look into that. ;)

Ah great.  Just when I got over my paranoia about my about my stand.  ':|'

Hehe, sorry ;)...Well, one thing that might help is making the tabletop "slip proof" so the rhodes cant move around so much on it. Since the stand is a pretty ok stand. I still dont think its great, but it does ok, as long as the piano sitting on top of it is sturdy, so it seems.
Ill heed your advise about bracing the rhodes down to the stand. I also want to put some material down on the tabletop to prevent the rhodes from moving on the stand.
And if it gets bumped again and falls, well, then the stands going with it, lol ;). Hopefully, it will be a little more sturdy when I modify the stand.
Thanks a bunch everyone! :)

I put my Rhodes legs in the closet... I've been using this:

It looks to be somewhat similar to the MK V stand.  It looks a little rickety, but it's actually quite solid, rated at 230lbs, almost two Rhodes!  Case in point, I bumped it pretty hard the other day, and the piano shifted on the stand, but didn't even come close to falling over.

Yeah, that's the same stand I have, and its the same stand that tipped, lol :p

What happened was when I bumped it, the weight of the piano shifted on the stand and started leaning backwards and fell. The rhodes took a super hard fall and almost fell on a guitarist. To me, that sucks, and that stand cant be the best idea for that rhodes. If the stand isnt somehow connected with the piano, the piano can move on the stand with a little pressure or force, causing the weight to be dis-proportioned. This wouldn't matter with a keyboard thats not so heavy, since it doesn't have so much weight. But this rhodes piano that weighs 150 pounds and is so massive in length and width needs something sturdier holding it.

Ah crap, that sucks. I thought the bottom would be thick enough, just taking out the old foots and replacing them with the flanges.
I'm not sure what other alternatives there is, all other keyboard stands seem too weak to hold the piano without rocking or swaying or giving out. I could look for an original bottom, but that still wouldn't be too sturdy.

So the other night, my rhodes took a hard fall onto the stage because the stand I had for it wasn't stable. Luckily, the rhodes is completely fine, and I am really assured that these things are built tough and made to last. But it probably wouldn't have tipped over and fell if the stand I had was more stable, or actually built onto the rhodes itself.
So I really want to convert this suitcase model into a stage model by attaching the necessary parts for the telescoping legs. But is this even possible? If so, what would I have to do? Also, are the legs even more stable? I would think so, since there braced onto the rhodes. They should be more stable than this cheap stand I have right now.

Parts, Service, Maintenance & Repairs / weird D key harmonic ping?
« on: June 08, 2010, 12:00:26 AM »
It is a treble note, and it doesn't have a clip on it. I think the grommets are quite worn, what are the symptoms of crappy grommets? and Ive been trying to adjust it differently for quite sometime, so that hasn't helped. It can only be something wrong with the way the tine is set up.

EDIT: Never mind, its not one if the treble keys, so it cant get a clip. Its an octave away from the treble section though.

Hi, I have this D key (actually, two I think) that gives of this weird ping noise when hit. I don't know what causes this, does anyone know? Is it a natural harmonic, or is there something wrong with the tonebar or tine?

Lol, well, its a very good idea jim. It only took a couple seconds to take the excess parts off, leaving only the adjustable pole. So far it has been pretty sturdy and durable and hasn't loosened yet.

I dont know how this rod would be for use with a stage model, since I dont know the size of the damper dowel hole in the rhodes. But this definitely works for suitcase models that are missing the bottom half.
I actually feel like I have a stage model now rather than a suitcase model!

I think they all are pretty much universal. I just had to take of the legs and top part and there you go, a simple rod.

« on: May 31, 2010, 08:13:41 PM »
Thats actually what I did, before I got the sustain pedal parts. I used delay and reverb to make some really cool pad sounds with the Rhodes. But it was no alternative to having actual sustain.
You cant control the effects as well as a simple sustain pedal. These effects still sound great with the sustain working, it gives the sound way more life.

I am very happy with my new sustain system. I am using a Vintage Vibe sustain pedal, and a music stand rod for the adjustable rod (Thanks to jim for that idea).
It looks like this system can last a long time, hopefully as long as the Rhodes itself has.
Thanks to all you guys for the helpful suggestions.  :wink:

But since I don't own a music stand already, I would have to go buy a new one or something. So wouldn't it be cheaper just to make a custom adjustable dowel rod?

If you buy a real pedal, make sure the pivot pins are in the center like a grand piano pedal  and not at the far end like an upright piano pedal.

Also..they are usually sold in sets of three......

I'm pretty sure the Vintage Vibe pedal pivots in the center of the casing, like most stage Rhodes pedals do. If you click the "sustain pedal" link in the first post, it will show you the pedal I would be buying.

For the rod, I would be using either a wooden or metal dowel rod and that would be adjustable and could fit in the pedal and Rhodes. I would like to use metal, just so its more durable, and it would consist of two pieces so it could have adjustable height.

did you play trumpet at high school? have a crappy stand?

No I don't have an old stand. I'm sure I could find one, but it might be easier just to go to the hardware store and get some metal rods.

Yeah, i figured that out, lol. I guess those big amounts of die cast metal are expensive.
What if i were to only buy the metal sustain pedal? Then could i just make my own dowel rod for it? It would be nice to have a good feeling pedal, that i know would last along time.

Hi, I have a mark 1 88 key suitcase model, and it is missing the bottom half, so it has no sustain pedal.
I was looking at buying the sustain rod for suitcase mods from Vintage Vibe, as well as one of their sustain pedals. Is this the best buy? Is there any other options out there that would be cheaper?
Thanks so much.
