||Re:Hey Doug- new Tone Stack|
I can't wait to try the new tone stack, it'll
have to wait until after Christmas though, (sigh)
I have a question if I may, What is the dc voltage
at the source pin of J5?
And is there no resistor or dc blocking cap
at the input of J5?
Thanks Ed R.

Looks great, Doug! For the life of me, I can't figure out that tone stack. But I'll give it a try. I might add a boost switch as shown on the MBM-6 mods. I think that work work very well with higher voltage.

Thanks for the comments, Jake.
Just think of it as a 2 knob tone stack with the Lo knob missing.

I haven't measured the voltage at J5 source. There's no blocking cap or resistor - it's directly coupled and it works. In rough terms, I figure the J4 drain should be swinging between 0 and 16V and J5 can handle 0 to 33, so there should be no problem.

But, could you though, please. (B+ at J5 source pin)
I won't get any more breadboard time till

I'll try to if I get a chance. I'm running into the Christmas rush here too.
