Re: 2465B CH1,2 compression

Dear Chuck rebonjour,

I thought so, and tested CH2 out at rear panel BNC, direct from CH2 preamp hybrid, it was perfect.

Before I pay $120 or more for the channel switch hybrid, I will swap out from a know working scope.

My other point: In the CAL procedure is there a vert CAL that somehow affects bias or other voltage dependent parameters in this hybrid? If yes can this be an off CAL symptom: I am using a swapped A5 at the moment with definitely wrong CAL parameters.

I really need a parts donor 2465B!
