Picked this little 1973 beauty up yesterday, fully discrete, trafos in and out, added internal pads, as I'm intending to use for line ins.

Cleaned up and sounding really good so far. :)

If anyone has a Schematic or any info, did get from google a user manual mostly in Japanese but with a useful block layout.

many thanks in advance.

I had one of these , many bugs so I ended up tearing it down .
I did finally find a schemo so pm me your email and I can send it .
The little transformers are cool . The inputs are  600- 3k  and the outs are all 600-600 .
The sub inputs are 600-10k . might try those in a BA .
