Mouser discontinued the DC 1 power supply production. If anybody needs a replacement board, it can be had from
It was $70 plus shipping. If anyone is looking for a Lexicon power supply, I would check there first.
My system has developed 60hz hum. I have traced it back to my MC-1. Can I correct this with a power supply replacement?
The hum is present with no inputs connected to the MC-1; disconnect the interconnects to the power amps and hum is gone. Tried different interconnects but hum remains.
FYI Pyramid doesn’t sell parts; Mouser doesn’t have the power supplies
suggestions are appreciated
DC-1 crapped out and was presenting a blank screen on front (all lit up, no letters/symbols). No response from any front buttons nor remote.
Replaced the power supply with an Artesyn LPT45 from Newark Electronics $55.77 + $10 shipping. Newark part number 62K3453. Arrived in three days.
Back in business. Replacing the board is exactly as @tadawson described. Easiest with a phillip screwdriver with a magnet head on it.
