Q & A / Re: Sunn 200s running on 6L6 tubes?!

Well i and the amp made it back to Germany safely. Got some KT88s and plugged it into my 110v step down converter.
There is sound, but a loud hum over it, that wasn't there before.
Opening it up it all looks original and pretty solid...
( Pictures not duplicated )
...but this here has broken, might have happened on the rough plane ride.
EDIT: resoldered it and now it's workig nice and quiet again!
Only the Lo and Hi switches don't change a thing?
My amp guy is currently on vacation, dammit.
So looking at the pics, is this an 8 - 4 Ohm output?
BTW yes all the pots are dated 1967.
Any other thing that jumps in your eye?
Thnx,
Pat.
It looks like your amp has been modified to have the 4 Ohm tap hooked to both output jacks with no switching involved. You can use either jack for a 4 Ohm speaker cabinet or use two 8 Ohm cabinets.
Other mods seem to have been done. There are two large resistors connected to the power tubes, not sure what the story is there. The three axial caps clustered around the original main chassis mount cap aren't stock. One of them says 150V so not sure what's going on with that. Then there is the black electrical tape, another mystery.
