I was offered a 1940s Cossor recently for £20-30.

Vintage scopes have market value for collectors.

If all you're doing is audio, any halfway sane scope will do that,

The range of frequencies found in audio electronics extends to frequencies of many MHz. Domestic AM and FM radio deceivers are considered "audio".

Radio microphones are considered "audio".

I'd call those radio myself


** Another asinine reply.

Folk who service "audio" are expected to do each of them.



Faulty ( or badly designed / built ) audio amplifiers may exhibit oscillation upto 50MHz.

which can be found on a low speed scope with a capacitor & diode

Digital audio seems to know no bounds.

though it doesn't normally tax any sane scope.
