Default Re: JVC HR3660EK problems.

At the base of each guide there is a small grub screw that locks the guide central shaft and these tiny screws have a habit of coming loose, thereby losing their grip to the centre shaft. After that due to the friction of the tape moving over the guide rollers, the whole guide assy can sometimes rotate and thus changing the tape path height and hence the tracking problem. Several tape machines can suffer with this issue, not just yours. Once you have everything set correctly you could try a drop of thread lock adhesive to try a prevent a repeat of the problem.

Something else that I've come across is wear and tear on the rollers causing them to wobble on their centre shaft. Also sometimes the roller can stop rotating freely on it's shaft, causing tape friction to turn the whole assy instead of just the roller.
