[A job for
Amp Repairman]
The owner of the amp said that it was working perfectly one day but when she switched it on next day there was no longer any sound from either of the speakers. The headphone output still works. I reckon there might be an anti-thump relay connecting the speakers to the output from the amp, with the headphones being fed from before the relay. A dodgy capacitor in a timing circuit for the relay could prevent the relay working? Unfortunately, she can't remember if there used to be a delay before the amp started working, followed by a click, then music. There is no click now.
The amp** was dropped off the other day. It is quite a nice piece of kit.
I took the owner's word about the fault and immediately took the cover off. Oh dear... it looked a bit densely packed in there! Nothing is as simple as the things I used to fix 50 years ago!
I confirmed that the headphone output worked. I could hear a relay clicking... Something occurred to me - I think the system had been moved from one room to another before the fault appeared and I wondered whether the owner had reconnected the speakers properly? I took the amp up to my speaker system in the attic room and connected it to them. I noticed that a CD had been left in the player so I span that up and immediately got blasted by Fleetwood Mac!
Hah! I gave the owner a ring to confirm that she would be home and cycled over to Hebden Bridge with the amp in my rucksack. We connected it to her speakers, and sure enough - it still worked. She swore blind that she hadn't made any mistakes connecting the speakers previously. TBH, I didn't give her any tips and I watched what she did; she did wire it up properly this time. Either she'd made a mistake last time or the amp has an intermittent fault which might come back in the future.
Anyway, that is one more job crossed off the long list of things that I have to do. I have NY retirement to prepare for!
** It is more than
just an amp - it is a receiver with a CD player built-in too.
