New member and I like the site. I'm looking for a schematic and a component diagram for a recently acquired Kustom III Lead S. I've never worked on a Kustom before and it is a little different than the other amps I have. It has an inspection sticker dated 3/28/78 and the board part numbers are PC5065 (PS), PC5129 (left channel) PC 5128 (right channel) and 009 52278 00 (small board to the left of left channel board). All of the boards are marked KEI-1. I found two versions of the PC5065 on this site but haven't compared them to what I have yet. Any help is appreciated.

The difference in the 10/71 5065 is that it's schematic is of the booster amp that was used in the second speaker cabinet in the 500 watt series amps since it has a power supply built in and a different input jack set up.
You should just use the early schematic unless you need to look at the power supply section.
