SERVICING OF A MUSIC ANGEL
Hi-Fi
AMPLIFIER
Another Chinese
Music Angel, this time with 845’s on the output. As with all
these Chinese amps……not bad, but always room for
improvement! Though, “looks-wise” they are pretty nice.
This one came in constantly
blowing the power fuse. It turned out to be main HT diodes having gone
short. These amps have a power transformer winding for 220 volt, which
is a little low for our 240 volt mains supply here in the UK. Whilst
generally not a problem, they do run a little on the hot-side with all
voltages being close to the limit on the capacitors!
Thank God for vacuum tubes (valves), beautiful!!
