Great post Frank.

Very neat and professional work Frank. Love the way you secure the caps with the wood.

reviving a bit of an old thread to get some input on how you guys handle trimpots in p2p work. Haven't spotted too many in audio builds and I was wondering if there was something more mechanically robust than the pcb-mount bourns parts we usually throw at the offset/balance. 

 

Maybe there's some merit in chasing down the cheapo pots on ebay?

there used to be chassis mount versions of the long 20 turn pots.

don't know if they are still available.

The Bourns 3590S are excellent and not too expensive.

There are mounting kits available from Bourns and or Vishay trimmers. 

 

Here's an example for the Bourns 3005, 3006 series.

Saw that a little while ago and thought, "Tango and James and Lundahl, OH MY!"

Pete doesn’t mess around.

That's what he has his raffle-dealer network headed up by DannyB for.

Beautiful work. Personally I'm happier to have circuit boards though, PTP is challenging, and limits your circuits to what can be sanely constructed PTP. But if you want to do it Frank has the right idea. Plan on iterating and debugging your circuit, do it first in a test bench then do a final transfer to the finished amp, if you want a polished look. 

 

Here's a version of the terminals I use which give you convenient ground lugs

But Frank, those you have are neat, where did you get them?
