The Wurlitzer Electric Piano / Re: Wurlitzer 120 Line Out
« on: August 11, 2020, 07:20:59 AM »
V V sells, or at least used to sell a little box with an input and an output that connects to the headphone jack of the early Wurli models. I bought one years ago and it works great, it was inexpensive (at that time) also. I'm not sure if they still sell it.

Great idea!

Using 200 style dampers usually works since they are taller.

I personally don't see why you can't use hardware store washers as long as they are the same size and thickness. Maybe try a few just to see, and also try filing the threads on a few screws to see if you hear a difference. That would be a big job to file them all though...

I think that is correct, but you should get more opinions from guys who are better with electronics.
It's been almost 25 years since I worked on electronics on a daily basis.

I hope that you found a volume control with the power switch attached.. follow the wiring carefully!

Unplug the piano and take a photo before you disconnect any wires from the control.

You do mean the metal cap and the brown one next to it and not the red disc cap, correct?

The metal cap looks like an old electrolytic. Not 100% sure on the brown cap, but you did say that the amp is working, so it is likely correct.

Is that red disc cap the "death cap"? It's hard to tell where it's connected. The disc cap is not polarized.

The death cap that should be removed connected to the AC jack or fuse on one side and chassis ground on the other. Bad news if it shorts out.

The springs come in different sizes, they don't all look exactly the same. The far left tines use larger springs, and yes, sometimes 2 on one tine like David suggested. You may be using a spring from higher up in the keyboard. Do you have any more springs?

Any speaker that is working will register continuity. The voice coil is just that- a coil of wire.
If the amp works, don't be too concerned with continuity on the harness.

The hum may be coming from the volume control. A worn control can cause this, but usually it is a loud hum.

It probably is best to leave it since it doesn't seem to be hurting anything.

Anyone else ever seen this wax?

The fuse should be inline with the hot (black) wire. Remove the "death cap" if it is there ( I didn't see it)  it serves no purpose. The green wire goes to chassis ground. In a modern, 3 wire socket, the black is the smaller prong, the white (neutral)  is the larger prong.  I do not know about the wax, I've never seen that.

From what I understand, the workers in the Rhodes factory were not trained piano techs, and tolerances were sloppy at times. A lot of times you will find the paper shims on top of the felt punchings on the balance rail. I was told they did this to save time, but to me that's just lazy.

There were several types ( felt, rubber, Square, angled)  and shapes of hammer tips, but I'm not an expert on the different types. The tips are different hardnesses throughout the keyboard- softer in the bass and harder (sometimes rubber wrapped wood) in the treble.

You can't align the hammers to the tines, but you can align the harp to the hammers a bit. (Strike line)  plus, alignment steps that Sean covered.

Tine #69 also looks pinned against the rail...
# 70 & 71 look like the pickups are too close.
A few other pickups also look too close below those.

I don't want to chime in on that one, my expertise is more on the piano end than the electronics end.
Sean, what do you think?

And new grommets too, I hope...

Some Rhodes pickups just plain die (coil opens up) and tapping dead pickups will not produce an amplified sound. That is how that helps.  It sounds like that is not your issue, so that is good. Can you post close up pictures of the treble end? It could be as simple as a strike line issue, or it could be broken pins on the plastic hammers causing them to go crooked, or it could be an escapement issue, or a combo of the above. Do you have the correct hammer tips on those hammers?

I think this last post was posted in the wrong spot...

What happens to the problem tine if you move the spring? Obviously it will go out of tune, but what about the bell like sound?

I've only changed one set of hammer tips and it was so long ago, I don't remember enough to answer your question. There are not many EPs in my area anymore, I don't work on them very often like I did in the 80's.
You really should ask Fred @ VV- he's a member on here. Search members under 'Fred-' and he will show up as a vendor. Or, call VV later today as Sean suggested. IMHO, I think you want a set of softer tips, but ask them to be sure. They works on EPS every day.

Strike line and escapement affect bark too.

Just curious, is this a stage or a suitcase?

Beat me again!

Ditto on all points.
Grommets for sure 1st. Hammer tips second. Hardened grommets will make good tines sound bad.

Lol. Sean posted as I was typing...

No, I don't think it's the amp. 30w should be plenty loud enough.  Are the ends of the pickups really far away from the tines? A previous owner may have moved those pickups back because he/she felt those notes were too loud.

The small bolt in the oblong pickup hole is the adjustment for this.

Different tuning springs have different color coding on them. Some are yellow, blue, black, etc. it has to do with the size of the springs. Larger in the bass, smaller in the treble.

I would try to find a felt strip to replace the strip in it. Putting individual felts in is not as easy as it seems. You will need paper shims to put under the green felts to adjust the dip. My local dollar tree store sells felt stick on pads like you put under furniture legs. They even have rectangular felts that may be the correct thickness, but you need to buy several strips to get the length. Of course this is just for the white keys.

It's possible that there is a bad connection, it's also possible, but less likely, that all of those pickups are bad. Do you hear anything through the amp if you tap on the magnet of any of those pickups? It should be an amplified thumping noise.

N.p. That's what we're here for!

Also, lessening the dip gives you the illusion the action is heavier, and visa versa for increasing the dip. Too much in either direction will cause issues, however.
