The Fender Rhodes Electric Piano / Cleaning oxidized aluminum on harp.
« on: April 18, 2020, 10:29:18 PM »
What works best. The aluminium is right up against the wood (obviously) and I don't want to discolor that trying to clean up the aluminum.

(72 Stage BTW)

Preamps, Modifications & Upgrades / Split harp mod?
« on: July 02, 2019, 06:58:17 PM »
So I have this 72 stage I'm getting back to working order.
When I got it there was a very amateurish preamp added (and additional hole drilled in the rail. One of the reasons it was cheap is because this mod was not fuctioning and the seller could get sound out of it.

Now that I'm close to done with the action mod and replaced a pickup (among other things) I trying to decide if I want to put in another preamp.

With a little guitar EQ pedal (from the harp) a little bump in the high end makes the lower half sound amazing. I mean this thing barks and growls! But the high end gets harsh. I tried mellowing it out with voicing but it just isn't happening.  So I was thinking that II split the harp i could easily design a preamp that would EQ the low notes only and then mix them back together.

Is this a crazy idea?

As far as the electronics are concerned I'm proficient in small audio signal design. Almost all of my guitar effects are either original designs or my take on classic circuits.

With the 1972 piano I picked up it had a package of spare tines stored in the lid. They are slightly different than what is in the piano in that the taper is shorter.

I had one tine that had the spring way out on the tip to get it in tune, so I thought I would try cutting one of the spares.
It functions, but it almost mutes when struck hard. The other tines sound awesome when struck hard. It almost sounded like a double strike. I put the original tine back in and found a heavier spring that kept it in tune without being on the very end. It sounds great.

So is that a bad tine, or can some of the later tines not handle as much dynamics? I'm just curious in case I pick up another piano with later tines.

I'm starting to tear down my 1972 piano. In pulling out the key bed I noticed these four screw holes under the keys. It would appear they would secure the key bed to the case but from the top instead of the screws underneath.

Were these used to secure it to anything else? Maybe to a bench when working on it out of the case?

(Just getting started so prepare for many questions to follow  :) )

Buying / Clean Rhodes 78 or ugly 72?
« on: March 02, 2019, 02:18:59 AM »
I found a local guy with two Rhodes 73 stage pianos. The 78 is super clean inside and out. Very well taken care of.
The 72 has cosmetic issues including a cigarette burn that melted a dent in a key. It also has an unidentified electric box mounted inside. I'm assuming it's a home made preamp, but i'm not expecting much. It's in a cheap project box with a two prong lamp cord. It also look like the power transformer for it is mounted inside the piano fairly close to the pickups.
The harp and hammers all look good though. I can replace the tips or at least the ones I see that have a divot in them.

Because I want a project and it's an earlier piano, I'm leaning towards the 72. He initially said $650 for either, but that was before I saw the problems with the 72. I might could try for $500.

Does that sound reasonable? The only thing I don't know how to fix is burned plastic keys and the scratched top (very scratched). but it would be a good project piano to get good at setting up. I fear the 78 is just nice (if a little too chimey) and not much adjustment would improve it.
