Anyone aware of anyone who works on synths in the greater Boston area? As usual, am trying to avoid shipping stuff if possible. I’d like to upgrade the power supply in an Arp 2600. Sorry, it’s not a Moog question 
FWIW, I know Georgia is a long way from Boston but it looks like Phil Cirocco sels new and rebuilt ARP 2600 supplies. Maybe you could order one and swap it in yourself?

From above site:
POWER SUPPLY UPGRADE - (ALL MODELS) - 250.00
The power supply in your 2600 is about 20 to 30 years old. Chances are that your power supply is not up to spec. This can result in excessive noise, ripple, and instability. This mod replaces your unit with a high power, highly stable, military spec power unit with remote sense regulation. The overall sound quality and oscillator purity are noticeably improved. Rebuilt ARP units are available for 125.00 (50.00 core charge).
Hello,
John Koumoutseas, of Syntronics still does synth work in the Boston area.
