I hope some of the knowledgeable folks here can help. I'm working on Thunder1 -RVT that's been somewhat hacked sometime in the past. There's no collector value, its in another cab, so my interest is in getting good functionality and tone.
I've got the schematic PDF that's around the web, unfortunately, many of the values are illegable, and some parts don't match my amp at all. (Reminds me of my vintage Gibson project).
My problem is in the tremolo circuit, part of which was cut out. I've got everything together so it looks right, except the pot labeled strength in the schematic.
Obviously, the wiper goes to the cathodes on the output tubes. One leg (which, left or right, if the pot is sitting on edge with the shaft pointing away from me?) goes to the plate of the tremolo triode through a cap and a resistor (values), where does the other go?
The schema shows it going to a little power supply off a third set of transformer windings, but there's nothing at all like this on my amp, and I can't read the voltage values on the line to the pot, so I cant hack something up.
Anybody seen one like this that's been built properly, or at least have a clear schematic?
Thanks for any help...
