Hi,
Unfortunately my power amp has been playing up for a while now and randomly turns itself off into self protection mode. Sometimes it works fine for a whole film, other times the fan comes on like a helicopter and switches off the amp after about 25 minutes. I replaced the internal fan and also added a AC Infinity cooler that sits directly on top of the amp to draw out any heat, neither made any difference. I took the amp back to where I bought it, they tested it in the store for quite a few hours, but couldn’t detect the issue. However, they only left it on at a low volume, so I imagine that was why the fault wasn’t discovered.
The amp is now out of warranty, so I’m not overly keen to have it repaired after the hassle it has caused me, also it’s an older model now and not worth much I just wondered what the best route to take would be now? Do I buy a better quality replacement such as the Anthem MCA 525, (but not sure if my current pre-amp would be good enough). Or alternatively, buy a second hand pre and power amp that are better quality, but with no guarantee or support if the product fails.
Any advice would be appreciated.
Thanks
Current setup:
Marantz AV7702 Control Amp
Marantz MM7055 AV Power Amp (Causing the problem)
Focal Aria 900 speakers (Front, Centre and Surrounds)
Rel S/3 Sub
