Power surge fried my MA5300

Andrew - most McIntosh gear has a factory reset procedure. Here is the procedure for the 5300 from the manual:

————-snip————-

Reset of Microprocessors

In the unlikely event the controls of the MA5300 stop functioning, the microprocessors can be reset by performing the following:

1. Press the STANDBY/ON Push-button until the

STANDBY/ON LED Indicator switches Off.

2. Then release the STANDBY/ON Push-button and the MA5300 will switch Off.

3. When the STANDBY/ON LED is illuminated press the STANDBY/ON Push-button, the MA5300 will resume normal operation.

Note: This can be performed with the MA5300 On or in the Standby Mode.

Oh no I did not see this and ChatGPT did not help either. Thank you for passing this on I will send this to the tech.

No idea. I first thought the Ethernet from the service panel but both Ethernet and Electrical devices were impacted.

I lost my Furman surge suppressor to a power surge recently. It saved my gear. I just bought a Brick Wall suppressor which does not use MOV's. The only thing that I noticed with it is that bass output is down a little. So I plugged my amp into my Tripp lite suppressor. The filtering of the low frequencies is a bit much with the brick wall. Too bad because the Brick Wall is a much better suppressor. I plugged my audio computer and my TT into the Brick and everything else into the Tripp lite. I probably ought to replace the TL as it uses MOV's which can only take a certain amount of hits before failing.
