NOTICE:  The tube prices in this catalog CANNOT be compared to others!! Each tube sold by 
V.T.S. has been LABORIOUSLY auditioned, scrutinized, and matched by Andy Bowman in the 
V.T.S. Analog Laboratory using National Institute of Standards registered gear. 
(See the Testing Laboratory, and Six Things, etc...)

Think these prices are high?  Try the "Crazies"

RCA                6L6-GC Black-plate at over $445.00 a pair.  That's over $220.00 EACH!!!!
                        For that price I hope the pins are solid Gold!  (And the box too!)
