Hi everyone-
Been a long time since I have logged in here.
Great to see so many Kustom enthusiasts in the forum.

I am helping a friend repair his Kustom IV Bass head.
His technician is telling him that the two power supply caps have failed.
The caps in there are two 9800uf 100V G.E. caps.

I have looked at various schematic data I have on hand and it seems to me that there were different versions of the Kustom IV Bass head. The only schematic I have that shows power supply detail is for a version that had two separate power amp output channels. The value of those caps is shown at 9000uf 50V dc.

I am wondering if anyone here might have schematics for this Kustom IV Bass that has only a single power amp output channel so that I can confirm what the original spec was for these caps?

Also any suggestions on modern replacement caps would be welcome.

Thanks in advance,
corona blue
