Axpona New York, held at Manhattan's Affinia Hotel opposite Madison Square Garden June 2425, was my daughter Julia's first audio Show. She and I followed the sound of Crosby, Stills, Nash, and Young singing "Déjà Vu"more real music!to the Empire Room, where Wharfedale Airedale loudspeakers were being driven by monoblock amps from a new company called Audio Power Labs. Each 833TNT amplifier uses a pair of 833 transmitter tubes, operated in push-pull and driven by a 6550 pentode. Inter-stage transformers take the place of coupling capacitors, and replacement tubes are said to be plentifuland reasonably cheap, at about $175 each. The 833TNT itself, which delivers 200W, costs a bit more than that, though: approximately $175,000/pair.
