I switched my tube system to separate units now using a Scott 350B. I need to check multipath distortion as in Tech Forum #7121, but wonder what bandwidth I need for a scope. I assume 100 MHz, but would a lower bandwidth (less costly) scope work okay? Would I hook it up as noted in #7121

The oscilloscope only needs to be flat to 15kHz, so almost any one with at least 100kHz bandwidth will work. I did it with one of the 5MHz/5" scopes that were readily available since the 1950s (Dumont, Eico, Heathkit, KnightKit, RCA, etc.). You should be able to find a used one for less than $20. The connections are the same: FM detector to the X input and AGC to the Y input.
