Anyone ever build a Marshall 18 TMB.......

A few mods.

That dirty 18 would have been better if it could go from a regular 18 watt amp to the dirty 18. I thought Zaphiod Phil had a similar circuit on the 18 watt forum?

Thanks for showing me the circuit Richie.

If you mean the hot switch or the one adding a gain stage that goes from standard type 18 to added gain stage. Yes there are many like that for other marshalls or whatever amp. Using many different names.
I think Doug Hoffman had a drawing of that too on his site.
many marshall mod places have similar things. Ace Pepper has some cool stuff on similar amps. The Dirty 18 has the trim pot,you can set it where you like. Then if you want just use a fixed resistor.

Like most things there are a few different ways to use a boost or added gain. Depends on amp, and tubes used circuit,to what you can tweak or dial in. You can go too far one way or the other. The trick is to get it to where you like the sound,and it doesn't cause the amp problems in noise and so on.

The Superlite TMB may have a plate driven tonestack, but the cascaded stages still delivers Marshall all the way.
