Vintage DD turntables. Are we living dangerously?

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.

The specs are for both the tt 81 and tt 71, the latter's specs being in brackets. So, he doesn't say anything about the tt 71's motor, since that is blank.

The only way to settle this is for Halcro to take his tt81 apart ;).

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

Living in the past and in denial, not dangerously.
