Some of it is just related to the old media compounds. Some is related to the tape hiss which was inherent with tape, wire, and ribbon recording technology of those days.

I enjoyed your video. Very nice, and the first time I’d seen the Roadrunner and psu in action.

I have OEM speed control on my main TT. It comes in the form of once per rev optical feedback rather than magnetic feedback. The unit is tied specifically to the brand, and is called the Radikal. I can check it with my Clearaudio 300 Hz strobe, but it’s boring since it’s quite firmly stable.

The other TT has an aftermarket speed controller from a guy in Hong Kong. His brand is Mober. He is using 16 times per rev optical feedback. It works very well too. Both kits include their own DC motors.

If I want 78 rpm, I trot out a third TT with an appropriate Shure cartridge for 78s. I don’t have many 78s (just my grandparents collections), so this works for me.

FWIW, based on my experience with PLC, SDS, and the built in ADS-like Levinson 515 controller, it is easy for me to understand why people are attracted to this SOTA product. Kudos to SOTA for making this available and retrofitting it to some VPI models. I am sure that I would be buying one if I still had a VPI TT.

Thanks. Mine wasn't working correctly at first. Christan at SOTA walked me through resetting the Condor and now 33, 45, and 78 rpm are all spot on based on the RR.

Hi edw,

Can you share what Christan advised on resetting the condor so that you are now spot on? Are you within .001/2 of 33.333 or are you seeing larger values. I know all is good +/- 0.005 of the 33.333 but just curious as to what you did to get you spot on and what you mean by 'spot on'.

Cheers,
Vin.

Vin, initially the 78rpm setting on the Condor was reading 80rpm on the RR. The 33 and 45rpm speeds were suddenly off too. After the reset (push + and - simultaneously while plugging the power into the Condor), it worked at all speeds, 33, 45 and now 78rpm. Running voltage at -3 for all speeds. Accuracy is the same as before (+/-0.001 or 2). All good.

Thanks edw and those readings are great!

I just recently got my bearing upgraded to the inverted ceramic ball bearing hoping I would get to those readings but still off by +/- 0.003 or 4 - maybe I need to put some hours on the TT for things to improve a little or it may simply be the belts causing the fluctuations - not going to buy new belts at this stage as I have barely put any hours on the ones I have!

Cheers,
Vin.

I wouldn't worry about +/- 0.0003 or 4 - well within the precision of the RR.

Thanks madrac. I have ordered a couple of new belts just to see if that improves things as I don't think there is anything else to adjust at this point. If it improves things great otherwise, will just leave it be at this point and enjoy the music!

Vin.

Thanks for the comments on the video...my first attempt.
My original speeds for 33.3 & 45 were correct, but 78 was high (80s). I found the reset instructions in the manual and then all 3 were correctly displayed. When I first turn everything on, the speed variation is +/- 0.005, but after some "warm-up" the variation betters to +/-0.002.

That's great just being off by +/- 0.002 - How long is your 'warm up' period? I am going to reset mine just for shits and giggles as I never have done since I purchased several years back and maybe that may help with my readings too...

Cheers,
Vin.
