Default What Oscilloscope specs for audio work, diagnosis and repair?


"Kannon Fodder"

Hi can someone please help me with what scope I should get for
Audio equipment repair? I need to have flexibility so I wont
have to buy another for a while. A benchtop model is fine.

I want something specifically to cover tube/valve amps.
I need to be able to check the performance of amp and see if
my input signal is distorting, deteriorating, has interference
or other types of problems that plague audio.

What the max MHZ range would I need to aim for?
What other features would it need or be handy?
Do you know a specific brand and model?
Do you think I need any other equipment?
Whats a good brand/model function generator?

Lastly I have read suggestions that I should get an older analog
scope for this work. And then read the digital ones "can" do the job.
It is a bit of conflicting information what do you think?



** DO NOT BUY A DIGITAL SCOPE !!!!!!!!!!!!!

Almost any ANALOGUE scope with bandwidth of 5 MHz or more is OK - DC
coupled or not.

Digital scopes absolutely SUCK for audio work.
