Problem ;-(

I skipped to this point, I like to read all of the input you gentlemen have but I just wanted to mention the one hand in the pocket rule. This goes with the very good advice Ray gave us. Never put two hands in an amp. Keep one in your pocket, you might get a bad bit with one hand in there but two the current goes around in and out passing into your heart. They might never get it going again. I have a tool to drain the caps, if any one needs to borrow it you are welcome. I rather see the mail man than your death notice. When you order tubes get a capacitor drain tool. They are not much. You can tell me and I will send mine to you.

No. So much information was coming at me I was swamped.
My understanding, not necessarily fact only MY understanding is ... It isn't worth the $ cost to convert to adjustable bias but by pairing the tubes with the capacitor the amp will run a little cooler. He said it was clear to him it's been running too hot.
It may be imagination but I think it sounds better, cleaner, more bite, I'm not good at explaining such things.

Sacrifice those tubes on the Altar of Tone....

Changing the capacitor in this scenario does not make sense to me. Changing a resistor, especially the resistor that sets the bias, is probably more likely what happened in your amp. The new bias resistor probably increased the bias of your amp. Therefore, the power tubes are running cooler... more headroom... punchier.

Anyways... whether it was a replaced cap, or a replaced resistor, or maybe your friend spilled some cold beer on it, I'm glad your amp is working better now. And, you didn't even electrocute yourself either... :cheers:
 
Good read.
Output transformer selection / size, and matching output tube impedance is still not clear to me for design / parts compatibility.
Nor is the concept on size vs output tubes / wattage, saturation, impedance, ability to drive speaker cones with respect generalizations about effect on tone, etc.

Reading this comment I'm thinking you are correct Sysco, "resistor" is now ringing in my ears.
As I said yesterday, "So much information was coming at me I was swamped".
