Vintage DD turntables. Are we living dangerously?


I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

Lewm, whilst the TT-81 has the identical positive and negative speed control in the servo detector......it does not have the coreless motor of the TT-101.
bestie, I think Halcro's response means you should not attempt a transplant.  It would be like putting a pig heart (or an "Abbie Normal" brain*) into a human, a willing substitute but not up to the job.
