Thank you, I appreciate all the helpful responses.

I tested the power amplifier with an expendable raw driver and found that the signal output was fine without damage to the voice coil, so I went ahead and connected the power amplifier to the loudspeakers in the second system. After connecting all of the audio cables, I plugged the power cord in, and after the proper 4 second soft start delay, the relay kicked-in and the power amplifier performs fine, with no sonic degradation as a result of the unknown issue in question.

At this point, I'm not concerned about the inability to power on/off the amplifier since I normally keep my solid state gear powered-on 24/7. The only concern I have at this point is the safety factor, and why the fuses blew in the first place. If I send the amplifier to Bryston's US repair facility for repair, the to/from shipping charges and Bryston's reboxing fee for return shipping are too costly for me to consider at this time for a second system application unless there is a significant safety issue.

Any further thoughts/insight are welcome. TIA

My only thought is 'if it ain't broke, don't fix it' . nt - 3+4=5 16:31:25 07/13/17 (1)

If the fuses remain stable, it's all good (nt) - Duster 16:41:21 07/13/17 (0)

Brystom has a Bryston only repair shop in New England. For all US products. - 3+4=5 14:04:25 07/13/17 (0)

My guess, with blown fuses.. switch and or relay is 'welded' 'open' - 3+4=5 10:54:42 07/13/17 (2)

good answer, but don't you mean welded closed? - madisonears 18:40:41 07/13/17 (1)

Was it unplugged while powered up? The pop of unplugging might have blown fuses? - 3+4=5 13:21:15 07/14/17 (1)
