The Wurlitzer Electric Piano / Re: 112 noisy amp issue - AMP MODEL SAYS 112A
« Last post by DocWurly on Yesterday at 09:28:03 PM »
Later 112's use amps labelled "112A."  That's fine.  Schematic attached.

I'm not a tube amp expert.  I recently toiled a whole lot on a 120 amp.  But there may well be others on this forum who know a lot more about the 112A amp (and tube amps in general).  It's one of the better-designed Wurlitzer tube amps--more sophisticated than the amp in the 120 and 700.

It could easily be a bad solder joint somewhere.  A resistor not doing its job.  I recommend checking your amp against the schematic and measuring the DC voltages at all of the test spots (the voltages in the rectangles).

Are you using all-new tubes?  Do.

Keep checking the whole system with the hum shield in place--without it, you will have a lot more hum.  And what happens when you detach the reed bar from the amp? Same hum, or less?

Voltages in this tube amp can be lethal.  Follow standard electrical safety up on them if you don't know them.  Never have both hands in the amp, etc.

Steve-o is correct --remove that death cap if it's there.  You should also 3-prong that baby ASAP.
If the ground wire doesn't work, it likely needs a new power switch/volume control. I've seen this happen a couple of times.

Also make sure thebleft damper assembly is connected properly- do this before turning screws...

I would not turn that nut. I've never had to. I just replied to someone else with the same question.

Have you tried regulating one or two dampers with the screw on the top (in back) to see if this helps?
You need to turn these screws (clockwise) very carefully so you do not break the stickers. Hold the stickers with pliers so you do not snap them.
The Fender Rhodes Electric Piano / Re: Tool For Turning Guide Pins

Piano supply stores generally only sell to working techs. There is (or was) a tool with a U shaped slot that was made for this, but mine broke years ago. This is a quick but  temporary fix. The only correct way to fix this is to replace the key bushings, but it's a big job. I would just use pliers and place a piece of leather or felt between the tool and pins while turning so you do not chew up the pins.

I'm pretty sure I've seen one in the past.  It looks like a large drum tuning key, but has a slightly oval shaped slot for putting over the pin.
Have you tried a piano supply store?
I understand, but the factory function is the same.
Are you unhappy with the action you're getting?
The Wurlitzer Electric Piano / Uneven sustain

Hi all - I seem to be having sustain problems on my Wurlitzer 200... the pedal appears to be working, but only on the middle and upper keys, not the lower ones. I've tried tightening/loosening the damper connection rod with a nut driver to minimal success. Any suggestions?
The Fender Rhodes Electric Piano / Tool For Turning Guide Pins

I apologize if this has been covered before, but after much searching I can't seem to find a solid answer.

I'd like to turn my guide pins to alleviate some side-to-side movement but don't want to use pliers out of fear of grinding them up.  Is there a recommended tool for turning these pins?
