Bryston 4b Help Left channel light stays red on start up

bambam · Sep 26, 2019

Hi,
I have an old 4b that i'm trying to get working again. The power switch on the front went bad so I ordered a new soft start board with the switch and soldered it in. The switch is working but now on the Left the led stays red - Any ideas of where to start troubleshooting? I haven't hooked up any source or speakers to see if it passes audio.
Many thanks,
J

Thanks Joe - any ideas on getting this fine amp in service again!

Welcome! Staying red I'd guess is saying it remains muted after start-up. Call Bryston service in Vermont - (802) 334-1201
