    So I came home from work at 1130 pm and was gonna play for a bit before going to bed and when I went to flip on the amp it was already on. The last time I had played had been the day before so it had been on (on standby) for at least a day and a half. The jewel light was not on and had no power.

    I checked the fuse and it was burnt on the side so after going to many stores to get a fuse (1.25 amp time delay) I came home and it blew the fuse again in less than a second. Tried another one and the same thing happened... The light came on for a second and it blew the fuse again.

    I understand that it could be the power tubes or one of the transformers, but how do I narrow it down?.. I don't want to spend a small fortune repairing it because a new mercurymag transformer costs 205-235 and I don't even know how replace that.

    Clifnotes:
    No power, blowing fuses...
    How do I find the exact problem?
    Any alternatives to mercurymag transformes?

    Unfortunately if it takes out the fuse in standby mode the transformer may well be faulty. Usually caused by a bad connection in the mains supply, IEC plug, lead etc.
    Disconnect the secondary wires, two violet one grey and two orange, then try again with a 60Watt light bulb in series with the mains supply, that will save your fuses.
