While troubleshooting a dual band mobile radio, I discovered the relay based attenuator in my HP 3336C was flakey. Saw a post on the HP-Agilent-Keysight Groups IO page of a guy that sells a PCB adapter that uses Omron relays that are still available. His pcb is for the HP 3325, so the spacing wasn't correct for my 3336C but it worked after shearing the board.

Well done Dave, they are nice generators and I've used mine a lot over the years. The attenuator in mine is still working properly, and hope it will continue to do so till after I no longer need it.
