The amp is still very bright and lacking (sub)lows. I guess that this might be due to the 20+ year old Sovtek 5881's (6P3S-e with the "coin" base). I even clipped the bright caps, but that didn't fix the brightness.

(My MIG has 100nF PI coupling caps and a few minor other differences from this schematic)
I was recommended the JJ 6l6GC, but the datasheet tells me that the tube might not be happy running on the MIG's 511VDC plate voltage.
Any other recommendations for a fat, "dark" 6l6 that can handle a lot of voltage?
