Gary:

My 390 had been off for about 2 hours so I just flipped it on and it was 23
seconds to signal.

Is it normal for a R-390 to take a minute or more to work after turning on?
 
It's working fine, I believe, but I was curious about the signal.  It has
static after normal warm up but it take another minute or so before the
broadcast band is heard.
 
I replaced all the power supply and regulator circuit tubes and found one
tube in the receiver circuit that was flaky.
 
All controls are working as expected.
 
Both meters work.
 
Replaced both dial lights, three resistors and two caps in the regulator
circuit and removed diodes in the power supply.
 
Should the oven be on or off?
 
Should the ballast tube run hot?
 
Thanks in advance.
