I have an ampeg B4 (older blue label model sn# AUSDKA08XX)
The frequency control knob for the crossover was broken off when I got it. I'm looking for a replacement. It's not a std style pot. There are 12 pins (4 banks of 3 pins) on it and a tag with
aB100KX4 .
I'm assuming this is a Bourns pot possibly? 100k x 4.
I cant find it in the schematics I have. Can any of the Ampeg gouru's help out.
I also need to replace the master vol pot (bent shaft) its a CTS pn# 70-103-22. Having trouble finding one ( fliptops dosent have either of them and that PN looks to be a special mfr pn# for SLM)
Any help? pics to follow. Thanks!
