What Oscilloscope specs for audio work, diagnosis and repair?
 

You should also get a potential divider for when working on the o/p area as
you are bound to have the attenuator set on the wrong scale ,some time, and
at least blow the first transistor.

You mean like a varible resistive dummy load for the output?

** No - ****wit.

The stupid pommy ASS is alluding to a 10:1 divider probe.

Look that up if you have no idea what it is.

He means blow the scope's input transistor/FET.

get a 10x probe;
it divides the signal by 10 and givs a higher input-Z,for less circuit
loading. it turns the scopes nominal 1 Megohm input Z into a 10 Meg input.
Less capacitive loading,too.

you can also get switchable 1X/10X probes,but they cost more and are more
trouble,IMO.

Another consideration for valve stuff especially, ie big kit, is the ability
to use the scope at the amp so being able to position it face up , floor
standing, is useful. A valvetester and also for personal safety a variac
plus isolation transformer and ELCB/RCCD/ GFCI
