hiho:
go to the 'specs' section of the page for the tt 81, here. For motor, it asserts: "FG detecting Coreless DC Servo"

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.

That specs page is for TT-71, which the writer is assuming its motor is similar to the TT-81 and I can say the assertion that it uses a "coreless motor" is absolutely wrong because I owned several TT-71 units before and I have looked into the guts of all of them, all core motors. I even looked into the specs pages of TT-81 and QL-A7 (uses TT-71 motor) from their service manuals and none mentioned "coreless" motor. Here's a simple proof. Just look at the first picture of the Amp8 repair page on a TT-71 under surgery and you can see the coils wrapped around the iron core. Axel, the owner and webmaster for vintageknobs.com might be an expert on Sony products but he's wrong on this JVC model. While the TT-71 is quite decent sounding, better than most Technics, it is not quite up to the level of JVC's other DD tables with coreless motor. The TT-81 might be a different story though and based on Halcro's testimonial he seems to like it quite a bit. _______ |
hiho, The english flyer for the jvc ql8 has a small black and white pic of the tt81 motor. Take a look and see if you can tell whether it's a coreless motor or not. |
More observations I made earlier in the other thread. Here's the major clue from the vintageknobs page. Halcro did post some innards pictures of his TT81 but short of the inside of the motor. That TT81 looks awfully close to the TT71 motor. Yes, Halcro needs to take apart his TT81 to settle the score! :-D _______ |
