[R-390] Penultimate recapping an R-390A

[Jerry K]

Whatever trips his trigger... but if I was going to all that trouble I 
think I'd have at least started with a St. J refugee or similar needy 
derelict instead of this nice looking SW--which probably didn't really 
need tearing down. I do agree that a product detector mod or accessory 
product detector is just a frill for these receivers. The 390A is so 
stable that just tuning the BFO for clean SSB audio always worked 
perfectly for me.
