Hello kve777, well the last time I used it I had to turn the balance to one side and hook both of my 901's to the same speaker channel, had to double them on the same connection point and it also seemed like the tape1 and tape2 control wasn't functioning correctly either but not sure how to narrow it down but as soon as I get new aux cords and speaker wire I am going to hook it up again to see about giving you better details. I also was running it through my kenwood ge-1100 equalizer I just want to make sure I don't have bad cables or something stupid. I bought all the equipment when I was in Germany in 1990 and I really loved it and would love to get it back in order. The main thing I want to keep is my carver 6250!!! Thank you for any help you can give.
