I'm replacing a volume pot in a mate's 80s QED amp, is a cheap one frmo Maplin etc going to be durable enough?
Alps pots are meant to be the best, no idea how much they are though.
£30 odd IIRC, well over the top here.
A very cheap pot will turn about 270 - 300 deg. A halfe decent multi turn pot of the correct value will be ok unless you're an audiophile super expensive set-up.
How do I identify a half decent one then?
It's a budget amp.
We always used alps when I worked at the recording studio.
Have a look at cpc or farnell.
Also make sure you get the right one....log or lin, and the right hole size !
If it be a volume knob then it should be logarithmic.
I had a QED MA34 Passive Pre Amp which had an Alps pot which was the point of the thing as nothing much else to it.
Arouund 10 quid for an Alps Blue on ebay. Or a variety here http://www.hificollective.co.uk/components/potentiometers.html
go for a stepped attenuator - get one from ebay
