Thanks people!
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.
For an amp this old, there might be other issues that pop up. Read through this thread over on the MEF board.

Those tubes are OK if that's all you can get, but output power is probably only 45 to 50 Watts. Probably needs to be checked out by a good tech.
Note: A 4 Ohm cabinet should be plugged into the "External Speaker" jack. The internal wiring should be checked to see if the amp is wired for 4 or 8 Ohm cabinets or 8 and 16 Ohm cabinets. There are pictures on this web site to check.
