[Milsurplus] R-390A Audio Improvements pages

[Hubert Miller]

I have one copy - four pages - of procedure for improving audio section of
R-390A.
By Thomas Bowes  KK8M, titled "To: All R-390A Audio Modification Information
Requestees".
Includes one 24 volt zener for V603A V603B 6360 cathodes bias.
I just noticed that title, it should have been "Requestors".  
Will mail cost-free to someone who can use this.
No reply from me means it is already claimed.
Your QTH with your FIRST email to me or you lose.
I think i have had this since the 1990s some time, and i don't think i saw
it on the net, in a 
very brief search.
