Now it gets interesting, I had almost the same discussion with an audio tube
fanatic friend of mine. When I told him about the "135watt/ 4x 6L6 twin, or,
for that matter, the "75 watt 2x6L6 Fender 75 combo", he just burst out in
laughter.
I'm not a technician, and I'll take anyones word that 4x6L6 give 85 watts
and no more. However, I didn't go around the world painting "135 watt" on
the back of all those Twins! so whats the story here? From what I get (from
ampwares and other info on the net), there are different breeds of SF twin,
commonly called "85watt twin" "100watt twin" and "135watt twin". I looked
at all the schematics and all I can tell is that the 85 and 100 watt seem to
differ a little, and the 135 seems to differ a lot, most notably the
different OT or OT-hookup.
If anyone could clear this up, it would be greatly appreciated, cause I'm
totally lost!
