Unfortunately I tried that and it didn't help - it was even at Pro Digital for a full service and cleaning maybe a year ago or so (and maybe only 50 hours or so put on the heads since then). What's odd to me it that it worked fine the last several times I used it both for mastering and for playback...it wasn't until I left it on with a tape in it for a week and then tried to use it that it work play a tape at all, relardless of the tape I put in it. In th epast when I've had heads go out on me in decks, it's been a more gradual progression then that, so I thought someone might have some insight into the potential ills of leaving a deck on for an extended perdiod of time like this. I thought perhaps the fact that a tape was in the deck resulted in the heads spinning for a week straight and wore them out or something like that, although I've never seen such a warning before.
