My wife asks me why I haven't bought a guitar in over a year. I think she has some shoes she's longing for...Anyone ever wonder if our spouses have accounts on this forum? Just for "lurking" purposes.

Let us know what you find. Did you try replacing the output tubes?
Oh yes. The fuse blows with no tubes installed. It's pointing me toward the power filtering section or the power transformer. I still haven't had a chance to dig in deeper.
Than I would say the power section is a good point to start with.
I would look for loose wires or pieces of solder that have shorted out across connections, to include the fuse holders and the amp's light.
I would then look for obvious "burnt" or shorted parts on the circuit boards, namely where the power transformer connects.
I would "lift" the wires coming out of the power transformer.
Does the amp's light come on at all?
Just one case for why one shouldn’t put off colonoscopiesI had that happen with a bad rectifier tube
That would be my first guess.I think that it is a bad rectifier diode that is taking it down.....but not sure yet.
Diodes was going to be one of my recommendations, however, anything can cause a short. It just so happens that I would recommend lifting the legs of the power transformer and see if you can narrow it down to a specific circuit, like the DC conversion/bias circuit. Kind of difficult to do with no schematic.
BTW-- their amps have had issues of all sorts. I kind of lost interest in turning mine on. I have a special 100 watt high gain run of the H amp, one of the original C amps, and an HX/DA with a tube effects loop.
Believe it or not, I am way deep into the 5150III 50 watters. That said, they have the thinnest circuit boards I have ever seen in an amp. But, I have had no issues with them at all.
My 2-Channel H issue is that I downsized my digs a couple of years ago, so I am short on space. I am reticent to part with the amp because I developed the Em7 Battery-less LED Footswitch Mod using it. To the best of my knowledge, it is the only 2-Channel H that has a Footswitch with LEDs that does not require an battery, that is, unless someone else implemented the mod that I originally posted here in 2012.
You got a quick link to that? I would do the surgery!!
