  Hi there - would like to report on my R390/A  -  after cleaning,  
partly recapping, replacing line filter with a modern one
  it was working fine - I was really happy. Switching on next morning  
it was working but audio was gone. Indication on
  line meter was OK as well carrier meter responded to  input from  
signal generator.Next day audio also was completely gone.

  No success with tube change > now proceeding according trouble  
shooting procedure - bulding tube test jig. Component test
  in audio module did not help.( did change out of range resistors ).  
Looks it keeps me busy - hi.
