Victor TT 101 vs TT 81
I always use a solid base because I like to be able to lock the tonearm to the chassis the motor is in, that's me and probably means nothing. Besides, I new I was using my 12" 3D arm so it became a moot point to have arm changing capabilities, I just swap armtubes. If I new how to post a picture I would do it, it really looks great. HW |
hwsworkshop well my ears tell me it means a quite a bit .... :^) @hwsworkshop Have you ever heard one of your tonearms in this fashion ? https://www.youtube.com/watch?v=HSZSzxnN1mg some fun many years ago now... |
Henry, et al. I thought you told us long ago that the motor of the TT81, while it may or may not be absolutely identical to that of the TT101, is also coreless. (I made a claim that it was not, which prompted you or someone else to post a brochure on the TT81 that seemed indeed to say it had a coreless motor.) In your initial post on this thread, I am unsure what you are saying vis a vis the TT81, coreless or not coreless? I do tend to like coreless motors, too, based on the performance of my L07D, as compared to my other DD turntables using multi-pole motors. Heretofore, I thought the major difference between the two is that the TT101 has a
bi-directional servo, can correct speed if either too fast or too slow,
whereas the TT81 servo is only reading "too slow". A question, if not a plea, to HWS: Have you got "a guy" who can work on my TT101? I'd love to get it up and running, and I have a pretty good idea where the problem lies, just not the knowledge to identify it specifically and fix it. So far as I know, it does not need a new master chip, but I do have a few spares of those, if that were to be the case. Like Halcro says, I gave a spare chip to another frustrated TT101 owner in Germany, still waiting for his results. |
According to the specs at Vintageknob, it is Coreless, but with substantially less slots (24 vs 180) TT 101 http://www.thevintageknob.org/jvc-TT-101.html TT 81 http://www.thevintageknob.org/jvc-TT-81.html |
VintageKnob is often an unreliable source. You can download the Service Manuals for both TT-81 and TT-101 units from Vinyl Engine http://www.vinylengine.com/library/jvc/tt-81.shtml http://www.vinylengine.com/library/jvc/tt-101.shtml which disclose that the 101 is coreless but not the 81. They BOTH however, share the bi-directional servo control (a Victor patent) which IMHO is one of the secrets to their exceptional performance. |
