I get max gain at full counter clockwise, and nothing at all from 12 o'clock upwards. I'm guessing I've wired the gain pot wrong. I've stuck with the conventions in the offboard wiring guide, and used the terminals nearest the knob as A and the terminals nearest the base as B, is this correct? If so, I've gone wrong somewhere else!Unknownhttps://www.blogger.com/profile/10132332727388880899noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-58583211806322833702017-10-23T09:16:33.023+01:002017-10-23T09:16:33.023+01:00That's something that's seen quite often -...That's something that's seen quite often - To have multiple filter caps in parallel.
