Removing the Reverb board from my DSL100?

[Jasonp]

Would it be possible to remove the reverb board from the amp just by not connecting it or bypassing it? If you switch it out on the back of the amp I'm guessing that it's switched out of the signal path?

The answer is maybe. Why would you want to do it? I don't have the schematic in front of me so it is also possible that the board has other functions (such as your effects loop) or has dedicated power supply/ground paths interconnected through it also. It probably won't hurt anything to do it and see what happens.

I tried it and it now turned both reverb knobs into two volume knobs.. that's interesting. Just by connecting basically around the board.

Here I beleive is maybe what you would need to figure it out.. http://www.drtube.com/schematics/mar...jcm2-63-02.pdf

I don't use the reverb on the amp and would like to remove it.

Connecting "around" the board?

I cannot for all the world imagine why you'd want to even bother removing it, but it is your amp.

There is a signal from the preamp, and an output from the reverb board BACK to the preamp. If you simple disconnect them, I don't suppose it could hurt anything. Might leave the reverb return stages unterminated and more willing to pick up and amplify noises. The wires carry the power voltages.

If you are somehow connecting the send and return together, I am not sure that is wise. All you are doing is connecting the reverb send branch back to the return circuit, so I can see how the reverb control could then control the level of that signal. But tehre already are existing volume controls, and this would not be adding much of anything, just acting in parallel with the others.

And since you already have done it, the point is moot.

I jumped from con8 on the upper board where the tone controls are to con8 to the lower power, pre-amp board.

[Jasonp]

It looks like if I connect con7 to con8 of the lower power/pre-amp board I could bypass the reverb completely?

Ok this must be the send and return. I just disconnected these two connectors and found that the amp works like it should and no reverb.

There is no reason to "bypass" the reverb, it is not a signal path through the amp. The input and output do not need to be connected. As you found, it makes the amp work funny. No bypass needed, since the dry signal circuit is already there.

I copy that.
What is really weird is that when I have the con7 and con8 on the pre-amp, power amp board disconnected the amp is a little louder. Other then that it seems to work good. The reverb must not be in series..?
I'm just going to reconnected it and stop dicking around with it and enjoy the sound. I really like the tone from this amp even if it's made like a POS.
Thanks for your help. I was hoping you would come into this thread.
