Weak Spring Reverb

[g1]

Thanks, at least I can stop troubleshooting now. The owner of this amp got ripped off, and not just for the wrong reverb tank. I assume you got that info from a website somewhere. Can you point me to it?

In case you were asking where I found that info about the Gibbs, it was a guy talking about the tank he pulled out of a Wurlitzer organ. Hammond organs also used the Gibbs. Here's the link:

" I make my own "bug" with a super-bright orange LED (yellow or red also work well) and the photocell sold by CE/Antique as a replacement for Morley pedals. Plus an inch of black heat shrink tube. An advantage of the LED is it reduces the click noise that accompanies vibrato use to an inaudible level."

I sure would like to see some more details on this trick!

I frequently rewind transducers and have a stock of 'pulls' that I've rewound and have handy when one fails. I drill the head off the rivet and wrangle out the transducer, rewind and reassemble with a 1/16" brass screw/washer/nut through the remaining body of the rivet. It means I can get a job wrapped up more quickly than waiting for a new tray.

I don't even bother to set up my pickup winder. I wrap a small drill bit with masking tape and mount the transducer onto this and spin it in my rechargeable drill. I use 42g for the output side (usually ends up about 220 Ohms DCR) and I think about 38g for the driver side. Neither is critical. If you wind the recovery side to as much as it will take then the reverb is much better due to the increased signal.

Only one detail remains, the long LED lead goes to the 100K resistor.

Then there's things I haven't tried, like green, blue, white, & infrared LED's. There's room to experiment if you like.
