Either Trichord or Tom Evans (when he went solo) offered an update to the Pioneer in the nineties. AFAIK it was only the replacement of a coupling cap with a DC-servo.

Default The Hitachi diagrams.

Hi Mikek ,
I had a virus on my system and it deleted several months of mail. So the scanned Hitachi 4700 diagrams were lost. I will have it done again and send it to you. Sorry for hijacking this thread.
Cheers,
Ashok.
