Mark Levinson 326s Shutting down

Hi guys,

I picked up a used ML 326S from my dealer last week and it is intermittently shutting down. The dealer is going to take care of it ( they rock ) but was wondering if anyone had any experience with this symptom? It either locks up, with no response and has to have the power cycled, or, it will just reboot on its own.

I have an Oppo 205 connected via balanced Nordost Tyr, power amp is a ML 332

Switched to another input

Swapped out balanced IC

changed power cable, and outlet being used

Offset is 0

Gain 6

I had it running 24 hours straight, no issue. Then it has shut down 2X in 15 minutes. Really weird.

I am dreading going without it now, it really sounds great.
