[Collins] kwm-2a problems

[Jim Brannigan]

Take a look at the power plug and schematic.  There was some wiring/straping
for 6/12/24 vac filament operation.

> Need a helping hand. all of a sudden lost filament power to all tubes
except the string consisting of v-7,17,5,13 9,10 and 8. I see they are all
in the same stringthe remaining string are also fed from the same pin on the
516f2 supply, pin 8and 9 are tied together ,per my schematic.have voltage at
both pins but no filament lite in the remaining tubes. I keep looking but
nothing pops out. see no burnt resistors,caps etc. I guess I need a little
steering in the right direction.Any help on this problem would be a great
help
