unfortunately, there's no manufacturer name or logo. it is labeled '5311 50KB1' on the bottom of the phenolic base (not on the metal or plastic body). the former is a date code, I'll bet, and the latter is the resistance & taper. thanks! -----Original Message----- >From: Brian Willoughby <xxxxxx@xxxxxxxxxxxx.xxx> >Sent: Jun 5, 2018 11:33 PM >To: Kerry Bradley <xxxxxxxxxxxx@xxxxxxxxx.xxx> >Cc: Analog Heaven <xxxxxxxx@xxxxxxxxx.xxx> >Subject: Re: [AH] Roland parts > >It also helps to look at the part.

It's that, or I'm gonna have to try to fix the trace or, just hardwire the VCA LEVEL function. Seems ridiculous to have to do this for a synthesizer that's essentially widely available!!! >>>> >>>> Thanks for the bandwidth. >>> >>
