I'm working on a 70's Kustom Challenger amp and have isolated the problem to a bad SE540L. It functions as a driver for the output transistors and has been obsolete for a long time. It is packaged in a transistor can with 10 leads. I have searched the web and come up empty, so I'm hoping somebody has one or knows somebody who does. Appreciate any help or advice. Thanks.
