Moving 50% off sale.

ONLY ONE PERFECTLY MATCHED & BALANCED QUAD LEFT!

Each tube tested 140 / 140 (max) on my Eico 667, I never had a quad where all sections tested identically, so I re-tested on a B & K 707, they each tested at

98 / 98 (max) on that tube tester!  $250 for the remaining quad or $125 a pair!

I am a former owner of the Canary Audio Mono-blocks featuring (4)300 B(s) per channel. (2) 6SN7 GTB(s)per channel, and (2) 5U4G,(2) 274(s)per channel. I have a matched quad of of Hitachi 6SN7 GTB, black plates, 1960s, chrome domes, with carbonized black plates at $250.00 for the quad, $125.00 per pair, singles at $62.50 These bested the "Holy Grail" of 6SN7 variants,the Tung-Sol 6SN7 GT, 1940s, black glass, black plates, round getters by a very wide margin!. This quad will give you optimum performance out of your Canary Audio amplifiers. Granted these upgrades are very expensive. Did you spare any expense when you went for the Canary Audio's in the first place?
