Mark Levinson 436 problems
one of my ML 436 amps shuts off about 3 seconds after being turned on. The problem does not exhibit when it is at the local dealer's repair shop, but always does so in my house. The amp is one of a pair; and each is connected to its own 20 amp dedicated circuit. The amps were upgraded a few months ago, but were behaving the same way before the upgrade. The other amp is fine. Does anyone have an idea of what may be going on? I would not like to have to buy a new set of power amplifiers. The ML 436 sound so magical when they work.
