Hi Hallams. Yeah, they updated the power supplies when I bought mine too. I bought mine from a film mixing house and they basically incorporated some of the 1200 upgrades into the supplies and other things. Other than that, the biggest upgrade I have is an Adams Smith Zeta 3 synchronizer. This gives me a nice modern remote, full sync capabilities,100 point autolocation and automated punching. It even automatically calculates the head gap and times the punch accordingly. Very cool.
BTW if you need any parts I have quite a large stash. PM me if you are needing or wanting anything.
Cheers, Les
