I assume you have not yet done the 2 ohm modification?

If not, that is certainly weird. Possibly a shorted output or something like that?

One of mine drew excess current when I got it and it was slow draw like your describing. It was out of alignment and the channel bias was in run-away causing it to draw more and more current until it pegged my bench power supply.
Now this does not mean there is not something serious wrong with it , there might be, but by your description this is what it seems like. Have you been tinkering around the two little orange adjustments located in each channel ??? The one on the vertical card is the DC offset, the one on the main board is the output bias drive adjustment... nether should be touched unless you know what they are and how to adjust them

OK it sound like something went south on you and the amp shutdown to protect, and now on power up it blows fuses STOP turning it on, it has issues and needs to be benched ASAP. If you keep replacing the fuses you will just cause more damage... It sounds like it has shorted devices inside it and they will only get worse if you keep trying. PM me and I will give you my number to reach me if your interested C
