You cannot view this attachment. I re-capped the power supply section and am still getting 50 V at point B. Any other ideas? Wondering if the transformer is shot...

If you don't have 200V at point B, there is not enough voltage for the pickup to produce any sound - just like a wurly.
Why not using the old / original screws?

Are they the thick ones (4,2mm) or the thin ones (3,45mm) diameter below the head?

The Wurlitzer Electric Piano / Re: Chopped Wurli Amp Issue
Last post by pianotuner steveo - March 21, 2023, 06:51:06 AM
Sound only going to one side of the headphones is caused by using stereo headphones in the mono Jack. Either use mono headphones, or replace the mono Jack with a stereo Jack, and be sure to connect the + audio wire to both + terminals.
Crackling noises in Wurlitzers can be caused by dust,dirt, pet hair or condensation on the reeds. Condensation happens when moving a Wurlitzer in cold weather, then turning it on too soon when brought indoors. Don't keep wasting money on parts until you are sure that parts are actually bad. Also, condensation can happen if you clean the reeds with compressed air.

If hammers are letting off too early, use the tool to adjust the capstan that trips the jacks. You will be turning the capstan clockwise (it's upside down, so left to right). Don't go too far or hammers may block against the reeds or even break them when hit hard. You may need to use long, needle nose pliers on the E and F n the middle of the keyboard where the metal braces are.
The Fender Rhodes Electric Piano / Re: Tone bar length table?
Last post by thebob - March 20, 2023, 05:40:49 PM
Near as I can tell the manual has the tine lengths (though these are in the form of an image/templates, not actual measurements), but I don't see the tonebar lengths.
Thanks for the tips!  The hum is gone, but there's still some crackling and fuzzy sounds most times I turn it on and play.  I have some time off work in a couple weeks so I'm going to replace more electrical components then.

I want to replace the can capacitors.  I ordered electrolytics with the same capacitance, but do you have any tips on where and how to mount the replacement capacitors inside the chassis?

Thank you, I see the letoff tool on ebay for the 720s.  Messaged them to make sure it'll work for mine, then I'll order it.
