[Collins] KWM-1 manual

[Dr. Gerald N. Johnson]

The scan that I received from someone on this forum only shows the tube 
sockets from below and the alignment points from above. No detailed 
parts locations. Its dated 2nd ed 11-57.

I see from the below picture that it has a boatload of black beauty 
capacitors. All color coded with stripes. I think the stripes are two 
digits, multiplier (in pf), then voltage in 100s of volts. So a little 
.01 at 600 volts would be coded brown black orange blue. A .1 at 400 
volts would be coded brown black yellow yellow and would be fairly 
large. They were leaky when new and are much worse now. Save much 
troubleshooting by replacing before testing. Each leaky capacitor will 
degrade the radio a little.

Looks like except for connections the voltages from a 516F-2 would 
supply the KWM-1 adequately.
