The Wurlitzer Electric Piano / Re: 120 model, not far off

That tape is gone with the death cap, it was just where they soldered a new lead from the fuse before. I will add wire sleeves. Yes i have worked on a couple, and completely recapped a push/pull first try recently. I had too many bad experiences bringing these to amp techs when i was younger 17 years ago. I know how to use a multimeter to discharge them yes, but should I be building some alligator clipped lead wire with a resistor? I use tools with rubber handles, work with one hand, and wear gloves. I never touch the leads with my bare hands.

I only figure its modified since there is an extra drill hole where I presume it used to be

The giveaway is that your pilot light is a jewel with an incandescent bulb behind it. The 120 amp has a neon pilot light. They're the same amp, but there is a significant difference in the wiring to the cheek block. Does your speaker plug into a socket on the amp, or is it wired up to the cheek block?

It has wiring to the cheek block no plug on the amp. Can't tell if the year says 1958 or 1959. I noticed the fuse holder is wired on the outside of the chassis which looks like it was done afterwards in the 70s or so. Maybe the death cap blew a bunch of them for them to move it? So is the .1uf 600v white cap that was wired to the fuse a still gonna be the death cap in a 700 amp?

No worries, i am taking my time on this one. I appreciate you sending that. And yes, i snipped that death cap right out of there. What's funny is someone mounted fuse holder to the outside of chassis so they could easily change them. Its the only mod i see non original in there. I ordered a Tropical Fish electronics replacement kit as well. Another oddity, i noticed that instead of 2 matched 6v6gt tubes, it sported one 6v6gt and a 6L6gc! Obviously not good for the amp at all.

Thanks pianotuner steveo. Are you the seller of the let off tool on eBay? Just picked one up, and i have been absorbing the service manual and schematic. Is the hand drawn part on the schematic a revision for a Line Out? I noticed none of my outputs liked my 30s PA amp

Hi all,
Finally, after getting rid of a 112 model 16 years ago (stupidly), I have purchased another Wurly. A 120 model! I am absorbing all the old posts here best i can. Few questions:
1. Death cap, which one is it? And do you just snip it out, or do you have to bridge a connection from where its cut? This amp is fairly quiet and i fear changing the tone by recapping it. Maybe just the power supply caps are worth replacing?
2. Damper rail - can i just take it all off at once? If so, how? I need to get to the reeds to clean any corrosion on a couple notes that don't naturally sustain long enough. I feel like in my old 112 it was easier to access.
3. Seems like when i blast the volume past 90%, the speaker lightly overloads and not in the good way only while played. However, i feel the new speaker replacement could help.
As far as the action, its pretty darn enjoyable as is. It was lightly used by a lady in a country western band in the 60s/70s!
