Re:Hey Doug- new Tone Stack
Hey Doug,  
 
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!

Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

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

Ed,  
 
 
 
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  
 
after Christmas.  
 
Thanks,Doug.

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