Pickmaster, do you remember noticing whether the Fuchs had that much less available clean headroom or overall volume than your OTS?
Definitely not!
Fuchs had loads of clean headroom and volume. Actually only problem with this setup was 2x10 cab. I‘m sure if I had 4x10 with good alnico or neo speakers feel of the amp would have being much softer and bigger. Usually 6V6 s sound very sweet and liquid.
Clean headroom from Fuchs 30 was good? I like many of the lower gain types of tubes, like 6V6s (6L6 family) and EL84s, but usually the amp is lacking a bit in the clean headroom department. Yes I realize to sound twice as loud as a 30 watt amp you "need" 300 watts, but I prefer 50s to 30s for the clean headroom. It shouldn't make that much difference, I know.
