I got this thing working for a friend. I think it's a solid 10 watts. It's got 2 by 8 inch speakers. Any use putting a 12 in there??
In any case the reverb is way too active and springy. Any way to reduce the output of that? Even a little is too much. How about a resister at the input stage? If so, how big??
Thanks,
Terry

post a schematic, I got bored trying to find *the right one*

Shooter is right, we need a schematic to know, but one general thing as I understand it, is that the reverb recovery pot is what sets this, and it can often be the source of where to adjust this. The more resistance there, the more you get of reverb. You could lower the overall resistance or change the pot. An example circuit I used had something like a 330k resistor in line with a 1M pot. In your case you may want to try reducing any resistors there or reduce the pot from say 1M to 500k or if it were, say 2M to 1M etc. Again, this could be WAY off without looking at the actual circuit.

If the reverb pot has a linear taper, replace it with an audio taper pot. May be easier said than done in a solid state amp.

Sorry guys. This is a Teisco Checkmate 88. It has reverb and tremolo. The "88" must refer to the two crappy 8 inch speakers.

I can't find any schematics online for the 88... Pictures may help? If you could build the schematic of the reverb circuit it may help?
