Default Show off your P2P wiring.

I'm trying to get myself spun up for my first P2P attempt on a tube amp and I'd love to see some shots of how others have done this. Close up shots of the business side of any of your tube projects would be greatly appreciated. I'd love to see what the newbies have done, and the experts.

Page through the photo gallery. You'll find plenty of examples of P2P wiring. You'll find examples of how to do it properly, and how to just connect the dots and hope for the best.

Morgan Jones has a book on building valve amps. It contains many tips - including tips for P2P wiring.

This is a gizzards view of a 200-watt guitar amplifier I built about two years ago. A fellow member of an Australian guitar forum challenged me to recreate one of the amplifiers I used to build in the 1970's, and this was the result.

13 pcs. all together. (just change the number xxxxx.jpg)

The main thing is that the lay-out should be done "in paper" first.
After this you can take the drill and go ahead.

That's some GREAT work. You don't happen to have some more pics of the build process, do you?
