[R-390] 390A ramblings

[n4tua at aol.com]

Friends,
Just been working on the 390A. Symptoms, low sensitivity. Did the Y2K, 
5.5.4 RF-IF gain test and could not get the required -7vdc from the 
diode load with 2uV into J103. I did have J104 shorted. I wonder if 
this should be shorted for the testing in table 5-5? I proceeded with 
table 5-5 step 8. Everything looks good through step 9. It seems that 
the line level is a good bit higher than the 0vu specified on some 
stages. Wonder why that is? On to step 10. This is unclear to me. The 
test instructions say tune KC dial above 900 to peak signal which is 
3mhz? This will have to be tried tomorrow. Sound like I may be going in 
the right direction? Hope so.

Good Day, Collin
