Linear Power Supply?

@lewm I was going to mention the Brinkmann tubed power supply. I’ve read that it’s better but I don’t recall anyone giving a good reason why it should be in this application. Now I’m a firm believer in tubes in the amplification chain of my system, but here we’re talking about driving a turntable motor accurately. So, as with the sparse info given on the Brinkmann the last time I checked, I similarly remain unconvinced about LPS benefits in this application. I’m not writing it off and I might just try it..

This is an exercise in frustration for me. A whole lot of words but no mention of specifically WHY and HOW. If I were interviewing someone for a programming job, they would not impress me with this sort of vapid marketing speak:

I am not knowledgeable enough to concoct an explanation for why a tube based motor controller might outperform a solid state one, for performing the function required in the Brinkmann system.  But I do know that such a rationale exists somewhere, if not on the Brinkmann website.  Several years ago, Mark Kelly, a very smart super-hobbyist, developed a tube based motor controller for the Garrard 301 motor.  Mark could give you reasons why he chose tubes for the application rather than solid state devices.  Prior to developing his tube unit, he had already perfected (and sold several) an SS motor controller for the 301.  He built maybe a dozen tube units before going in to business building and selling wood bicycle frames, in Australia.  But it ought to be repeated that none of this has any bearing on the Eclipse system, where the issues are different, and we are only talking about a PS, not a motor controller.

when i had an origin live turntable, the single most noticeable upgrade was to the power.  after replacing the wallwart with a transformer, everything audible improved and til this day is the apex of my musical experience.  and, til this day, i don't understand why a single transformer that powers the tt's motor could alter its sound so much.

Viggen, Sounds like in your case the wall wart WAS a transformer, only. That’s different from the situation under discussion where the wall wart is a complete power supply, meaning a transformer plus the downstream parts required to generate DC at a particular voltage and current.
