To whom it may concern: I have just listed the original Harvey Rosenberg booklet in an Ebay auction.
NYAL booklet- Any value
I have a 118 page booklet called "Understanding Tube Electronics"--- A Study In: Natural Harmonics Audio, written by Harvey Rosenburg Of New York Audio Labs in 1984, apparently just after Julius Futterman passed on his rights and patents to his OTL designs. I was wondering if this would be of any value to a tube afficianado or NYAL collecter.
