I am working on restoring a Technics RS-671US and I am having an issue. When you power up the deck the left channel needle gets pinned into the red with no input and when play is pressed the tape will play at a low level with a constant 3.5kHz tone in the background then stop and eject in about 10 seconds. If anyone has had an issue like this with any tape deck can they let me know. I think it is in the transport.
