    It gets hot after a short time and blows the fuse. Both 4 and 8 ohm loads.
    ....I am intending to take it to a new local guy that came highly recommended.....But before I do, I would like some up front knowledge... Thanks, Bob

    Maybe bad poweramp tubes? I think that may cause the fuse to blow, at least in Marshall amps.

    If it's getting too hot, your bias circuit or the output tubes have drifted in current draw; might be also be a problem with the balance control. Could be as simple as a single bad output tube or loose socket. Shouldn't be too difficult if the amp's not doing anything else funny.

    I took it to the tech that re-capped my V-4 and he ran it for a while. He couldn't really find anything wrong so he put an adj bias and new JJs. It sounds awsome. I won't know till Thursday's practice.
