Default 'buzzing' amp - worth fixing?

I have to say I really like the sound of that. Is it easy to remove &
replace said transformers? I have a feeling dunking it in situ might be
beyond me.

Many transformers don't have any means of tightening them - the core
laminations are clamped together by the bent metal cover. In that case
you may need to find yourself a small G-clamp to fit over the lams,
and just leave it there.


I have previously 'cured' buzzing transformers by dunking them in a
tin of varnish. Is this out of fashion these days?

Anyone trying this does so at their own risk!

** Dunking is a last resort if the tranny has no bolts.

It will have to be oven baked for hours afterwards to dry the varnish - at
no more than 130 degrees C.

If you do not have the necessary knowledge and experience to know how
to disconnect, remove, replace and reconnect the transformers, it is
probably best not to attempt this. You run a real risk of either
damaging the equipment or electrocuting yourself.

Sorry it this appears unhelpful, but mains electricity is dangerous,
even for people how know what they are doing.

That's not unhelpful - that's good sound advice. And having taken the top
off last night and failed to see any sign of tightenable bolts or indeed
where I might attempt to mount a G clamp, I've decided to cut my losses and
dump it. Sad really, it made a great sound. But on balance I've decided the
answer to the question I originally posed in the subject line is - for me at
least - no. But thanks all for your suggestions. Interesting at the least...
