The SP-20 does not have an outboard PS nor does it have quartz lock.
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.

Hello Lewm This one is the one I just finished on Saturday, this is one amazing table. Total weight with the Steve Blinn large Isopeds, (highly recommended btw) is 88 Lbs This plinth is also available for the Mk2, below is one that I recently delivered to a customer, this one had the Stillpoints Ultra 6 for footers, also highly recommended but more than 3 times the cost of the Steve Blinn Isopeds https://systems.audiogon.com/systems/4909 The Victor is a work in progress :-) have not had the time to look at it for the past week or so - have you got yours up and running, if so how do you like it ? Good Listening Peter |
@lewm while the first sp10 released in 1969 the SP20 released in 1976 This is what i have about Technics SP-20 from this source: forgive me for google translate from Japanese: And high performance at that take advantage of the development know-how of the SP-10mkII, Quartz phase-locked control DD turntable. Starting torque 1.5kg · cm, a large turntable of its own weight 2.5kg (inertial mass 345kg · cm2), and to rotate at a constant speed in a quarter rotation from the start. Due to the large starting torque and powerful magnetic circuit, there is no change in the rotational speed using 150 pieces of the tone arm of the needle pressure 2g. In addition, it is also possible to use a cleaner during a performance. With pure electronic brake to provide users with a smooth stop of the turntable. It has adopted a strobe LED illumination by fringes of Article a row. Finish and has prevented the surface change and wrinkle finish was special surface treatment of the aluminum die-casting. TECHNICS SP20 PRICE: 60,000 yen (1976） Driving System : Servo Controlled Direct Drive Speed : 33-1/3 and 45 rpm Platter : Aluminum diecast 32cm, weight 2.5 kg. Starting torque Characteristic : 1.5kg × cm // Less than 0.7 （90゜） second to reach normal speed (33-1/3 rpm). Load fluctuation : 1.5kg x cm within 0％ Rotation speed deviation : ±0.002％ Wow & Flutter : Less than 0.025%（JIS C5521）wrms. S/N Ratio : 60dB（IEC17B） // 73dB（DIN45539B） Power Consumption : 4W Inertial mass : 345k × cm2 Outline Dimensions : 368.5 × 99 × 368.5mm Weight : 8.0kg I assume this is not as good as SP10 MK2 for sure, but must be better than old classic SP10 with different (older) platter design etc. |
Lew if you’re not familiar with gun metal CU-500 mat from Micro Seiki i’m pretty sure you know at least their CU-180. However the CU-500 is thicker and heavier (2.7 kg) and very rare along with their super heavy gun metal record clamp Misco Seiki ST-20 (not as easy to find as Micro Seiki ST-10). I don’t have any pictures of my stuff on audiogon, but this is picture of my own Misco Seiki CU-500 to check in high resolution on SP10mk2. And this is another view on the same CU-500 on the same deck. And old picture of my teak wood plinth for SP10 with EPA-100 and Technics EPC-100c MK3 cartridge retipped by AXEL in Germany (curently for sale or trade btw:). |
