| Vintage DD turntables. Are we living dangerously? @best-groove, if one uses threaded rod and a couple washers and nuts in each of the three mounting holes, you can lift the entire unit up a good 12", leaving room directly underneath. This is why the cables harnesses are so long - so the main boa... | |
| Vintage DD turntables. Are we living dangerously? Sadly, Lew, a fair number of serviced units aren't in calibration either. Freeze spray helps, as does not being afraid to twist the board back and forth a good 30 degrees or so. This will likely cause more joint issues, but they were about to bec... | |
| Vintage DD turntables. Are we living dangerously? Conversely I've been in to a lot of units for various reasons that appeared to be working fine that weren't. The good DD circuits are great at compensating for all kinds of ills. I've seen grossly miss-calibrated drives where the motor was fight... | |
| Who needs a MM cartridge type when we have MC? I really like those racks. Nicely done. | |
| Technics SP10 MK3 bearing and lubrication Not replaceable; you’d be SOL. I’ve left the world of the semi-retired, and now work 60+ hour weeks, so working on others ‘tables isn’t something I do often anymore - simply no time. | |
| Technics SP10 MK3 bearing and lubrication I tried to make some up a couple weeks ago, but my hot air rework station went out. | |
| Who needs a MM cartridge type when we have MC? They’re original, though the ones I bought all collapsed after a couple hours of play. | |
| Who needs a MM cartridge type when we have MC? Sure, I’ll take a look, though I’m rather content with my cartridge situation. On the other hand, one never knows...I’ll surely put one of the XL-44 on my PS-X9 after I refurb it, though that’ll be awhile. I’ve 8 ’tables ahead of it. I’ve a contac... | |
| Who needs a MM cartridge type when we have MC? I've a couple XL-44 and an XL-88D, all sealed NOS. Perhaps some day I'll decide to take the hit and try them. | |
| Vintage DD turntables. Are we living dangerously? I don't typically document jobs I do for others. Lots of things can contribute to an over-current protection, from intermittent connections to poor calibration. I very much doubt your issue is being caused by the motor. | |
| Upcoming Technics SP-10R (100th Anniversary Model) The arms intended for the SP-10s were 10". | |
| Vintage DD turntables. Are we living dangerously? Yep. | |
| Vintage DD turntables. Are we living dangerously? Yes. Someone had been in that motor and broken a coil wire and damaged the bearing, all of which I had to repair. | |
| Vintage DD turntables. Are we living dangerously? Here's the other side of the board: http://fidelisanalog.com/wp-content/uploads/sites/3/2017/09/IMG_1633.jpg | |
| Vintage DD turntables. Are we living dangerously? Three hall elements = hall effect sensors. They control the commutation. If the display blanks and the motor coasts to a stop, the over-current protection circuit is being tripped. This is a picture of the sensors - the windings are on the other... |
