Trace	Re: Diode clipping // Marshall Amps... David; That's great!! At least you are getting closer to what you want to hear. That's what counts. The caps will help when you pop them in there. Trace

David Manson	I've finally gotten hold of some caps... dont know the exact brand,, little yellow paper tubes... anyways.. I decided that the first caps in the amp would make the most difference so I tried switching them ,, the change was very small.. it did cut the bass a little.. i switched a .68uf for a .003uf.. what i really need is some sockets so i can solder them together and interchange things fairly quickly.. I think the next place i'll try is the caps by the cathode resistors,, or i'll go back to the diode section,, that seemed to make the most difference in the sound,, I also got some audio taper pots.. 500k's.. plan out putting them in place of the tone section pots i have already.. i think the mid pot is 220k and the treble is 100k... anyone switched the pots before??

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.

Trace	STEVE A.... DIODES ON PLATES Steve; I'm sorry!!!! I was falling asleep when I last replied. You were correct, the stripe goes on the tube's pin. It goes to ground when using it on a cathode resistor. Sorry again!!! Trace
