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!

At the risk of stating the obvious, early Michell Engineering turntables had AC motors, newer ones (2001 onwards?) have DC motors. Consequently, if you have a pre 2001 GyroDec, the standalone upgrade PSU Michell Engineering now sell (HR Power Supply) will not work with your TT.

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.
