the 2sk146v's behind the big Wima on those should be worth a bit by now.
You got the original output devices with the boards, Hardi ?

Why do you like these archeological finds, guys ? Reliability of these things will be problematic.

The LFA-150 isn't too bad, pretty normal and not weirder than it can be built by modern parts.

No, these are missing for both amplifiers, but i got 10 "nos" 2sk146 , a torodial transformer, and some large caps with it.

it seems that the blocks have been stored on a wet place
, and i am not shure whether i should ever use them in any coming "projects".

...the previous (unknown) owner did a weak soldering job
