Help with replacement Yamaha TRB6PII pots

[Joebass]

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!

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)

Thanks very much!
Yamaha tech support seems the way to go then, although I might change the preamp for a Glockenklang instead.

If you change the preamp bear in mind that you also have a piezo which won't be accommodated by a standard preamp configuration.

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.
