HP 3335A Repair - Part 1

As part of my auction score I picked up 2 HP 3335A Signal Generators. It turned out that one of them wasn't working so we'll find out which one and then check out the power supply (first rule of troubleshooting). We'll also look at how they work from a high level and comment on ECL. Auction Score video (@3335A) -    • HP Auction Score - Part 3
