Re: Looking for rear feet for 2465 DVM scope
Oh no, NVM that I see that it's one of the hybrids, not a regular IC. I may try reseating that and see what happens. If you remove that and power the scope up with it out of circuit will that cause

Re: Looking for rear feet for 2465 DVM scope

Re: Want Front Cover 2465b
