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.

No - last Wayne posted they use a stainless steel platter that they had made with a BA Mat 2. 
Hi,

I just bough a refurbished Denon DP-80 TT from Japan on Yahoo auctions. The seller is a Denon tech and for JPY 16,000 (about US$150) he will replace all caps, diodes and key transistors and also service the bearings and motors. DP-75 is JPY 14k. So fo Denon DD fans, there is now hope to service and rescue these great direct drive TT.
I am now looking for a plinth. Can PBNAudio make me one? The Denon DP-80 has the saucer shape like the Victor TT-101. In fact the Victors copied the Denon look. I have a copy of the DP-80 mounting template.
Driveman, can make any plinth you'd desire - but you will gain much more from removing the DP80 from its tin pan.

This is what I do with the DP80's

For the Victor TT101 ill make something similar to what I make for the Technics platform as its much harder removing it from its top plate with all the electronics mounted in the bezel around the circumference - sh should you choose to keep the Denon in its platform  Id recommend something like that, remember that you will need a 12" arm in this scenario - a 10" is too short and will interfere with the 14.5" diameter of the platform.

I was incorrect about the SP-20 not having quartz lock. The motor is also brushless.

Hi Peter (pbnaudio),

I'm defintely interested in converting my DP-80 into a similar version of your Groovemaster DP8. How do you compare your DP-8 to your SP10Mk3? Also can you make a 2 arm version of your DP8? I'll send you a pm via your website.
