    Hello,
    Is it OK to run an amp at full volume? The amps I am referring to are as follows;

    Silvertone 1482
    53 Tweed Champ
    40s Orpheus (no model number)

    Kind Regards,
    Steve

    I do it all the time. If an amps in good shape then rock out but if its not then pushing an amp hard has a tendency to make bad or weak components show themselves

    The only amp that I have on your list is the 1482 and I have run it full open many times with nary a problem.
    My 1481 is almost always run full volume and I think that is close to a Champ circuit.
    The only problem I get when running my amps on 10 is from my wife.

    It's a bit harder on the output tubes, but otherwise no real problem.

    Consider that the line supply voltage is about 10% higher than these things were designed for; that equates to 20% higher power dissipation. Therefore all else being equal, things will run hotter.
    Are these amps properly earthed?
    Does that 40s amp have a power transformer, ie is it an AC/DC type amp which derives the B+ directly from the line?
    Best to get a tech to check these things over, there could be plently of mission, even safety, critical items on the verge of failure.
    Speakers are likely to be a weak point, the old glues tend to dry out and the joints fall apart.

    It will stress them more. Some amps can take it, some amps can't.
