I recently experienced one of these wonderful amps Jacques, and
they are gorgeous! Really punchy low end is how the owner described
it and he was right! We compared against a Beomaster 3000-2 on phono
and the 5000 was clearerin the top end too! The potentiometers are
easy to pull apart and clean, just watch out for those little springs
and make sure they go back together the same way!
Hmm, there wasn't really anything I could do to the one I saw
apart from replace the amp trimmers and give it a checkup. The caps I
spot checked were fine.
Oh I am not sure if there is some asbestos inside these units
between the main PSU cap and the transformer though so please be
cautious there!
I am sure Martin will have the lamps (not to mention lots of
invaluable advice as usual!) which are not exactly common - 60v 5w
MES types! I got mine from a lamp specialist in the UK.
Lovely amps which I myself have overlooked in the past. I will
probably be on the lookout for one myself now :)
