Sota Cosmos

I bought a second hand Cosmos with the Fountainhead plinth (series 1)  and an SME V. I ask owners out there of older Nova's or Cosmo's, if they are satisfied with the original configuration or did they upgrade? The upgrade option at Sota to an Eclipse configuration is 5k to 6k (I think), which is much cheaper than buying new, but it's still a lot of money that could buy other brands. I am at a crossroads of sort. 

I have other tables but I haven't compared them yet, so maybe you've owned these and have compared:

Nottingham Interspace w/ Heavy Kit

JVC-QL-10

Technics SP10mk2

Thorens TD-124mk1

Dual 721

I only list these because in the near future I am going to have to pair down to two ir just one, hence the Cosmos question 

Any insight would be greatly appreciated!

On repairing your SP10.  From your description of the problem, it seems your table may have a defective IC that is alone responsible for speed control, if it's a Mk3 rather than a Mk2.  JP Jones of Fidelis Analog has re-created that chip using discrete components, and it fits right into the outboard motor control unit. Fidelis is out of business, but if you can contact JP, he may be able to help, at least by providing a chip which you could have installed elsewhere.  Simple, really.  I would start by trying to contact JP via the Fidelis Analog website, if it is still up. If it's a MK2, then I would still start by consulting JP.

Agree that it's a pretty drive from MSP through central and southern WI. I live not too far from Delavan (home of SOTA) and the storms and tornadoes have ravaged southeast WI and northern IL the last week like I've never seen before. Good luck with your new 'tables.

I hope that everyone in the area did ok. I didn't realize that you get storms like that all the way up there. While I traveled through there I had to stop for a burger and custard at Culver's, because I am from Culver City, in Los Angeles, CA.

Thanks for the suggestions!! 

I have the mk2 so I think the chip swap doesn't apply to that edition. The speed goes really fast on 78, the other speeds it's fine. I have been suggested to recap the power supply, and if necessary, the motor. I would probably need to bring it to a tech, as I don't have a DIY setup currently or access to oscilloscope (which I read is required). 

Fidelis Analog no longer provides restoration services, only the chip when in stock.
