Tandberg 1500 series
I recently restored two of these tape recorders. Both came back because after some time, both were exhibiting a vibrating noise, like a bearing.
In fact it wasn't a bearing, the noise was coming from the drive belt which was wildly vibrating.
I've no idea what is causing it or why its only when the machines have been running for some time.
Taking a leaf out of Philips book, I noticed they have little brushes which the belts run through, I have devised a similar arrangement and if successful will post some pictures tomorrow.
In the meantime has anyone had this problem before? What causes it and is there any other cure?
