nopants Posted June 11, 2015 Report Share Posted June 11, 2015 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? Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted June 11, 2015 Report Share Posted June 11, 2015 there used to be chassis mount versions of the long 20 turn pots. don't know if they are still available. Quote Link to comment Share on other sites More sharing options...
spritzer Posted June 11, 2015 Report Share Posted June 11, 2015 The Bourns 3590S are excellent and not too expensive. Quote Link to comment Share on other sites More sharing options...
Mister X Posted June 11, 2015 Report Share Posted June 11, 2015 There are mounting kits available from Bourns and or Vishay trimmers. Here's an example for the Bourns 3005, 3006 series. http://www.digikey.com/product-detail/en/H-83P/H-83P-ND/388693 Quote Link to comment Share on other sites More sharing options...

Earspeakers Posted July 16, 2015 Report Share Posted July 16, 2015 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 http://www.mouser.com/ProductDetail/Keystone-Electronics/827/?qs=sGAEpiMZZMvz8LftK4jertCfhuxrwt2WUEp7yhBoVA8%3d But Frank, those you have are neat, where did you get them?
