I have a kit available which does what you want but it isn't easy to build.
Would your kit also work with papst motors found in Empire turntables?

Not to hijack but Mark Kelly do you have an email address or anything? There isn't one on your website or anything a bit frustrating.

I normally have an ad on the classifieds at Audio Asylum but I have withdrawn it whilst I am busy with vintage.

It will be back up when my workload reduces to sane levels - I expect that to be sometime in late April. I have 42 wines actively fermenting at the moment so I'm as busy as a fly in a bottle.

I don't broadcast my email address due to spambots.

Hi
I built a power supply using two crystals. It works really well. It is speed stable and provides great base control in the music.

I can not remember the actual values of the crystals at the moment but if you want to build this type of supply I will take off the top cover and check the crystals values.

I do - somewhere. But I built this some 10 years ago and I will have to look for it.

Actually I built two and they are still in use on rock turntables. The change they made when fitted was probably the biggest change I have heard form any improvement I made to the turntable.

I live near Max Townshwnd who designed the deck and he agreed that ac speed control does make a great difference.

I have a Rock in storage (vinyl is out for the time being) as well as the Merlin PS for it. Makes a difference. Terrific TT too.

I also have a 240V rim drive design I want a PS for and Mark's solutions are tpically well thought out, so I'm interested in that rather than merely cloning the Merlin.

I have two TT's I want to try with a precision PS.
The first one is an Thorens 160 Super:

Mark was just mostly wondering if you still sell these kits? Well obviously you do the AC but was also wondering about the DC control you have on your site if you still sell that kit. I'm interested in them. I haven't decided if I want an AC or DC motor yet though.
