Hitachi D-3500 Cassette Deck, searching manuals for...
I am looking for the service and user manuals on the Hitachi D-3500 Cassette Deck. Mechanically I have been able to restore it by dismantling, cleaning and lubricating it were necessary. I also replaced most of the belts. The problem that I have now, is that it is noisy and humming away on the electrical side and the calibration device only works very erratically. I have searched the internet for information on this deck, but have found next to nothing on it, except that this and the Akai GXC-325D were the first “affordable” 3-head design cassette decks (actually “pioneered” by Ed Nakamichi in 1971/72, as far I know) from about late 1974 > 76.
I'd be very pleased if somebody could upload the manuals or any other information on this machine.
Thank you in advance.
