Joebass Posted May 18, 2016 Share Posted May 18, 2016 Hi, Does anyone know where I can get replacement pots for a Yamaha TRB6PII? Here's a link to the owners manual http://www.manualslib.com/manual/908931/Yamaha-Trb-6pii.html#manual Any help would be much appreciated!

ikay Posted May 19, 2016 Share Posted May 19, 2016 Probably best to contact Yamaha tech support. According to the TRB-P service manual there are four different pot types: Vol - 5KA (presumably 5K audio but that's an unusually small ohm value) Bal - 20KB (dual blend pot - presumably 20K lin) EQ - 50KW (same pot for T/M/B - presumably 50K lin) Piezo mix - 20KB (presumably 20K lin) So depends which one needs replacing. It's not clear from the tech notes whether the pots are mounted directly to the circuit board or not (in which case you'd need a different different type to a regular free standing pot) Quote Link to comment Share on other sites More sharing options...
Joebass Posted May 19, 2016 Author Share Posted May 19, 2016 Thanks very much! Yamaha tech support seems the way to go then, although I might change the preamp for a Glockenklang instead. Joe Quote Link to comment Share on other sites More sharing options...
ikay Posted May 19, 2016 Share Posted May 19, 2016 If you change the preamp bear in mind that you also have a piezo which won't be accommodated by a standard preamp configuration. Quote Link to comment Share on other sites More sharing options...
Joebass Posted May 19, 2016 Author Share Posted May 19, 2016 Thanks. I've never found the piezo to be very useful so disconnecting it should be fine. I'm leaning towards changing the preamp; having the option of running in passive mode with a tone control is a very attractive. Quote Link to comment Share on other sites More sharing options...
