Yes or maybe just get a new fan. They are a not a rare item.
I concur with the others. You should feel a good steady stream of
air out the side and whilst it is not loud, you can definitely
hear it running.

Hi all,
I'll condense this. A friend just
got this AL-80B that had?at one time
melted a filament tube pin. The tube
socket, the type that the socket is
on a circuit board, was burned
pretty badly. He got a new ceramic
socket. I did what I needed to do to
install it including getting the
grids grounded, socket properly
mounted etc.
Amp works fine now but I noticed
the cooling fan is basically silent
and seems to barely spin. When
holding my hand?on the output?vent I
barely feel any air movement. I've
never worked on one of these 80B's
before so I don't know what's
normal, however I feel this isn't
moving nearly enuff air.
I know this is hard to put into
words?but can anyone give me some
kind of idea of how much air can be
felt blowing out of the vent?
I know the fan worked normally at
one time because the inside of this
amp was full of dust etc! Actually
it was disgusting! It took me quite
a while to get it clean.
Thanks all.
