I posted the following on rec.audio.tech and rec.audio.misc:
I am trying to restore a Sony TC-630 reel-to-reel recorder. It records fine,
but after I play the recording for a period of time, say ten minutes, the
speed starts to slow down and gets worse with time. After turning the unit
off and letting it rest awhile, the speed is correct again for a time, then
slows down again. I have lubricated and cleaned everything that I should.
Any ideas???
I got several answers to my posts, including one that referred me here to homerecording.com.
One of the answers suggested that I may have a motor getting really warm from poor lubrication. I thought I oiled it, but I am a novice at this. I may not have done it properly. Can anyone tell me how to properly lubricate the motor? For example, do I have to completely take the whole chassis out of the case to access it? And anything else I may need to know.
Thank you so much,
Steven Schreiner
