Thanks for the heads up on the sticky thread. I have gotten a decent crash course on tape care, but this really helped explain the "why" in the maintenance. One thing that piqued my interest was on the calibration of the machine itself. I have a Pioneer RT-701, which I find to be a well made machine, but the electronics I feel are old, and really have no reference or baseline of operation. I am waiting on a custom tube head amp(can't wait for that:) But it begs the question, that while I am not really concerned with updating the internal audio electronics, who repairs and services the mechanicals of these machines that truly still "knows" how to work on these machines. thanks.Kris
