[Collins] Restoration of Collins 20V-2 Ser.# 260

[Keith Sorensen]

Greetings,

I am in the process of bringing a very nice 20V-2 back to life on the
original Freq. of 910 KHz, I do plan to convert to 75M next but want to get
solid results on original Freq. first.  I am finding a few problems with
wiring inconsistencies in the primary HV circuit breaker S107 to K102
contactor. The original schematic (fig. 7-7 main schematic) was taped to the
back door dated 61/62 and appears to be the original. Does anyone have the
complete manual for down load that matches this year? I have the information
provided on the web site, but this is a later revision. My set has the
original Mod trans 4 terminal. The Plate on light remains illuminated after
the S102 20 amp breaker trips.. The schematic indicates the lamp should drop
out with the main plate breaker tripped; I have to open K102 by pushing
plate off to extinguish the plate indicator lamp??? Thanks for your
comments..
