Hello Everyone. I am new to this forum.
I have basic knowledge of electronics and can desolder and solder nicely. I still work on vintage tube radios. So “Gurus" at this site please help me step by step to troubleshoot this AMP and repair?
Thanks in Advance.
I have this AudioSource AMP 300, which has developed following problem:
Upon powering up, it turns on with Blue light. Sound is great on both*channels*for about 1-2 minutes then it clicks off sound but the light remains Blue. If I re-power the Amp again it plays for 1-2 minutes and clicks off again.
I did check the AMP, disconnecting all the speakers and inputs. Still relays trip after 1-2 minutes.
Couple of things I noticed:
1. Even after the relays trip the Blue Light remains blue.
2. It is happening irrespective of selection of speakers A or B or A+B. Or even without selecting any speaker set.
3. There is a switch at the back for Trigger - Auto ON - Manual.
When the switch is on Trigger (Light is Red which is OK),
when it is on Manual (Light is Blue which is OK too).
But when the switch is on Auto ON (Light should be Red as no signal is coming in but the light remains Blue)
Looking forward to bring this AMP to life with your help.
Thanks,
Ash
