I have it in swedish but only the article from 1991 which was the same design but class AB.

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.

 

[jacco vermeulen]

Looks like this one didnt even make it to the starting line, Pavel.

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

Hello,

You got the original output devices with the boards, Hardi ?

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

LFA-Class A

Hello Hardy ,
do want to build this Amp ?
You can contact me by email walter_burkhardt@web.de
regards Walter

 

[jacco vermeulen]

Walter is saying that this can be built as the LFA150 or the 50 watts class A LFA50 . I liked the LFA50 more.

 

[amplifierguru]

I have the first part (incl schematic) of the article (Elector Nov'88)in English. Don't have a scanner though but can answer.
