Just got a Sherwood receiver (DAS RX-206ORDS) - quite nice, sounds
excellent - flawless - until it's been playing for around 45 mins, at which
point a buzzing begins inside the box. It's loud enough to be annoying.
Seems to be very localised - this is a ten year old beastie, all bits & bobs
rather than circuit boards - and my instinct is that it's one component in
there that's gone dodgy. Might it be worth repairing? Is it something I
could do, with a bit of common sense and a soldering iron? Or is it landfill
time? (I don't want to waste time & money on it, but it goes against the
grain to just junk something that's basically very good and, apart from this
one glitch, totally sound. Any help/advice appreciated.)
