Vintage Gyrodec TT power supply question


I may be acquiring a Michell Gyrodec from a family member but have been told that it is missing the power supply. My questions are:

1) Can a replacement be found?

2) Is there an upgrade replacement available?

3) Is it not worth it?

My current TT is the Pro-Ject Debut Carbon with acrylic platter and Ortofon 2M Blue. I've read a little bit about the Gyrodec and it looks and sounds like it is killer table with a lot of upgrade possibilities but I'd like to get a sense of how difficult / costly it may be to even get it up and running.

Thank you for your responses and insight!

boywondr84, sure can, a lot more expensive than just replacing the power supply though. Have you checked which motor you have? Two ways to do this; send Michell Engineering your deck sn and they will tell you. Simpler, look at the motor, if there is an approximate 3cm knurled nut where the drive shaft protrudes from the motor housing, it is a AC Papst synchronous motor, if the spindle simply emerges from the housing, it is a DC motor.

@mgattmch Good catch. I didn’t even consider the older Papst power supplies.

@boywondr84 Both of my links above are the newer DC power supplies,

@elliottbnewcombjr  posted the link for the QC power supply which I believe is an upgraded Power supply for the older pre 2000(?) Papst AC power supplies. These are considered "vintage" so you can’t buy them new.

I find this reference useful: https://www.angelfire.com/music5/michell_gyrodec/ it may help during assembly.

Let us know how it works out. I’d especially like to know what year it is.

Good luck with the Gyrodec, you’ve got several Gyrodec fans rooting for you!

OP, if your Gyrodec has the Technoarm 2 tonearm, it has a habit of fraying at the RCA connectors -- it’s a continuous cable. It happened to me and the result was the left channel coming in and out. Just something to look out for.
