Resistors, Yes!
Hey Bro,  
 
The restors are great. Very quiet! I used one of the 21K's as the as the screen/phase inverter power supply de-coupling resistor, and two of the 8.87k's as the voltage divider for the bias supply on my Plexi. I also put two 464 ohm's in series for each screen supply. I recommend them.

most excellent. i know i like em. and in my tests, they will dissipate 3 watts w out a problem. could probably get 5 watts out of em if ya gooped em up w heatsink compound, and put an aluminum plate underneath em.  
i still have a bunch, if yer interested in a full set. the values can come in handy.

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.

Re: Foot switchable clipper circuit
Hi Bill  
 
Did you use a cap across the V2A cathode and what neg.feedback resistor-cap/tap did you use ?  
Most of the time my customers and I do get plenty gain/drive with a pretty stock plexi circuit and a post PI mv . With a non bypassed V2A cathode and a 0.0047 bright-cap I do get nice lead-sounds with the volume between 2 and 5 .  
Not to offend you in any way !!!

Hi Chris,  
 
None taken, Thanx!  
 
I have discovered that my 335's pick-ups were on the low side. Plugging in a few other guitars brought out a nice sweet grind. In retrospect, this is exactly what I need, as I can always bump it up a notch with a tube screamer, etc., and have a nice fat tone for clean playing. As for layout, it's 1987 except a 100pf instead of the 5000pf on the bright volume. I did have a pre PI master volume, but I didn't like the change in tone so I ditched it. I used a .68uf on V2A, 100K series resistor and 4ohm tap for neg. feedback, 440vdc on the plates, -41v bias for 40ma per tube. I tried 50uf, then 100uf on the plate supply, went back to 50uf as it's a hair looser in tone. The amp made it's debut last night at Sly's in Monterey. It was the Bell of the Ball..
