Hi,
Looking for advice...
I'm just trying to fix up my old JP601 turntable to see if I can make it a goer. I don't have much vinyl left, but it has been playing it OK until now. I got Tivoli (local hifi store who also do repeairs) to check the electrics and they fixed them up OK (so now it's not going to zap me). But I have a list...
1. the rubber mounts (3) for the motor are shot. They were conical 'pull-through' ones that were probably fairly specific, but I'm guessing I can get some soft-ish, thick-walled rubber tubing and cut to size to form the suspension. And a couple of sorbothane 'washers' to isolate the rest of the motor. I've also had a suggestion to stack grommets (which appeals to my cheapskate nature).
2. the motor is a bit noisy (and according to Tivoli, a little fast), but I think I can build a sheet to cover the hole in the platter mounting tray. I just have to locate all my sound-damping sheets...hmmm! Also suggested is oiling the motor after cleaning - is standard good oil good for this or do I have to buy expensive snake oil?
3. the spindle and bearing could probably do with a clean, so I'll try pulling that apart and see if it's "Cloth Ears" fixable or cleanable. Is there any special grease I should use for lubing it once I've removed any dirt. The bearings must be fairly small, as the tube holding them is only about as thick as my thumb. Ditto the oil/grease for this?
4. the feet I put on about 25 years ago are shot, so I might by some Sorbothane ones from Decibel. Probably 5, as I think the corner with the motor in it will need 2 (I'll have to weigh each corner first).
5. and probably a big piece of damping material on the floor of the unit (which is currently only 3mm plywood).
With luck, I can do this all for about AU$60 and get some improvement. Obviously the motor being a little fast cannot be helped, not that I've noticed it much - most of the vinyl I have is not what I have on digital.
Of course, the best advice would be to go and get something new! Or old, but better. But I'm cheap and I kind of like the way it sounds now. Stopping the mechanical noises would be a step up...
