I finally got around to buying a scope yesterday (Tek 465B), and in looking thru the specs in the manual, it states that the max input voltage (for either DC or AC coupled) is 250Vp plus the peak AC voltage, or 500Vpp.
I intend to use this in some upgrades to my tube preamp; I would like to take a look at AC ripple off the filter caps in the PS sections, one portion which is at 425Vdc, the other which is at 250-260Vdc or thereabouts. I know the second one should be OK, but what about the first?
When I was a tech, I didn't worry much about it, since it wasn't my scope . Now that it is, uhhh...
Thanks,
Chris
