Hey
Bruce, the preamp section is fine, I use the preout to drive a seporate amp. Works fine this way however after doing some research on the F-FET feature, I've learned it was very unique and I'd like to get it up to it's full potential and see (hear??) for myself if a V-FET output amp will share sound qualities as tube gear. There's no output from either channel and I haven't had it apart in a long time, I've read this model is known for biasing problems. That said, I have Full service manuals in pdf or tif for:
Eico HFT_90
Eico HF_52
Technics SA-5770
Marantz 1060
Harman Kardon 330Aand Schematics for:
Sansui 1000A
Eico HF-81
It's not a lot I know, I don't sell this vintage gear... I just keep them and rotate them as my main system. If it makes any difference, I'm non-profit and doing a pretty good job at it!Thanks for any/all help
John
