Hi Roger, you might speak with Ned at Triode Electronics, as he has worked on Stereo 70s and such for years. If needed, contact me offline and I'll put you in touch with someone in our area who may be able to help. Good luck!
Hi, One place I would highly NOT recommend in Chicago, would be Martroy Electronics. While I have no doubts they can fix it, they'll also take you to the cleaners on the cost. They've done it to me, and another friend of mine. Try $60 to replace a AC Cord on a Scott Tuner for myself, and $200 to lamp a Sansui 8080 reciever for a friend! Avoid this place like the plague!
