I'm working on getting another from a member here, that will justify the risk of opening one of these up. I got a service manual which certainly is a requirement (Thanks, Charlie!!!), I have replace surface mounted parts on my sony D6 DAT, as well as my sony d6 cassette deck, so I am aware of the difficulty. I'm older now, shakier hands and failing eyesight! (lol). Should be a good experience if nothing else. I'm sure a repair would be costly. Thanks for info, everyone here has been great with help. Bob
