I'd like to know what the minimum useful bandwidth is for an oscilloscope
to be used for general TV and audio equipment troubleshooting and repair.
I've stumbled across a 20MHz dual-trace scope at a second-hand store, it
appears to work and they only want $50 for it. The brand is "Leader"
which I'm not familiar with. Comments?


About 10 to 20Mhz is adequate for most CRT TV diagnosis, in my experience -
the more experience I gained at servicing, the less I needed a scope to
diagnose most day to day faults. IMO it might be better to get by as cheap
as possible until you assess the requirements for servicing flat panel TVs,
there might be other instruments that prove more useful than a CRO.
