Tektron Reference TK Ultimate 2A350M 300B Monoblock Amps Excellent with original packaging, with KR 300Bs. S pecial screened low noise Mazda 6J5 diver valves can be switched to 2A3, 50 or 300b valves.
Compared with a sensible solid-state or integrated alternative at £4,000, this is on the ambitious side rather than a bargain, because the recent comparable asking prices cluster lower with a median of £3,166 and a 75th percentile of £3,807. It is only a little above the top of that band, so I would treat it as stretching fair if the condition is genuinely clean and the seller is credible, but not as an obvious value play.
What makes it appealing is the usual 300B/2A3 monoblock draw: big, dimensional midrange, excellent tone, and a very direct, low-power presentation that can be magical with the right speakers. If it’s been well cared for, complete, and properly set up, that rarity-and-performance combo is the upside here; just make sure tube health, output transformers, and any included spares or original paperwork are all in order before paying up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Tektron Italia traces its roots to 1991, when Attilio Vittorio Caccamo founded the company in Italy after discovering the allure of vacuum tubes while repairing vintage radios as a young enthusiast. With over 35 years of hands-on experience restoring antique radios, Caccamo channeled that passion into crafting hi-end audio gear, emphasizing heart, soul, and meticulous Italian design. The brand's heritage lies in this artisanal evolution from restoration to bespoke amplification, producing their own transformers—often by former Bartolucci craftsmen—for unparalleled quality.
Tektron focuses exclusively on vacuum tube amplifiers, specializing in Single Ended Triode (SET) integrated models and preamplifiers that deliver warm, enveloping sound. Their lineup includes standout designs like the Neptune Reference from the Masterpiece Series, featuring pairs of 211 power tubes and 6SN7 drivers for high-fidelity performance. Parallel Single Ended options cater to speakers without extreme efficiency, such as non-horn or full-range drivers, while prioritizing NOS and modern tubes for optimal musicality.
Positioned firmly in the high-end boutique market, Tektron commands reverence among tube aficionados for its no-compromise builds, with flagships like the $19,500 Neptune exemplifying rarity and sonic excellence. Exclusive distribution in markets like the UK underscores its niche appeal, attracting discerning buyers who prize Italian craftsmanship over mass production. Tektron stands as a purist's choice in the competitive hi-fi landscape.
