I am trying to help a friend on the west coast identify a problem which
keeps burning up a 2.2K 1/2 watt resistor.
This resistor is on the B+ line and located to the front of the electrolytic
C-94 and comes off the center section of this capacitor along with another
2.2K, several red/white wires and a couple other resistors.
The one in question goes to a terminal strip to the front of the
electrolytic and is joined with a white wire with red and blue tracers. This
wire then goes into a small but tightly laced bundle where it goes
somewhere. The "somewhere" will lead me to resolving what is causing the
extra current draw and burning up the resistor but I can't find the wire
without cutting the lacing on my receiver which I really would like to
avoid.
Fro the schematic, there appear to be at least nine, 2.2 K resistors that
are possibilities and I eliminated them I thought from the rather poor
pictures in the book but I was wrong. I thought it was R100 but that is not
it. Others seem to be R31, 26, 22, 21, 12, 52, 47, or 84. I may have missed
one as well. I have a picture which I can send if that will help identify it
but I need someone who has more information than in the manual to point me
in the right direction.
Thanks, Roger NJ2R
