I ran across a very interesting schematic for a single-ended Plexi with a pseudo-phase inverter for a presence control and extra gain. The schematic is attached.
I have a couple of questions, and will need some help on this:
1. Would I be able to use the Hoffman stout chassis for this build? Will there be enough room?
2. I need some help converting the schematic into a PTP board layout. If someone could help me with that, I would very much appreciate it. Thanks so much.

The Stout should work fine, tight but works, I've built 2 amps on the chassis using 2 pre, 2 power tubes.
download dougs plexi6V6 layout, then with your favorite editing software cut/paste the "new" values n components. I just did a 2ch twin type layout based off somebody else's layout that was close. take your time, re-work as much as needed on paper so you don't have to do it with solder!

Just as an FYI, here is a link to the webpage where I found the schematic and a write-up on the amp. There is also a clip there which sounds pretty good:

Cool site, thanks for the link! His projects all look pretty interesting.

hi Big_Mike. the link you posted has a layout already there.
its just under the schematic...
with respect, Joe

Thanks, I totally missed the link to the drawing on his site. I will try and convert his tag board into something more compact to use with the Stout chassis.
