Thanks again guys! The 2247A has been running overnight with signals in each channel and everything has been humming along ok, no lockups.
I'll put it on the bench sometime today or tomorrow and check the DC voltages per the service manual and check for ripple. I'll have a look at the diodes and check their marking and see what's what.. If any electrolytics require replacing, will this throw off the calibration? I don't have any of the fancy gear to do a proper calibrations (PG506A, marker generator, etc).
I have a really nice 2245A and enjoy using it and always wanted a 2247A. This particular one seems to be clean and in very good condition overall. The trigger section on the 2247A seems better than my 2245A as well. The 2400 series scopes look nice but the 224x's are probably more scope than I'll ever need. I also have a nice 2232 that I like using for the DSO section. I mess around with building synthesizers and the 2232 is nice for catching really slow events.
Thanks again!
