A beautiful pair of tested, matched genuine 1950's era all original Western Electric 300B. Study all of the photos below and view test reports. These are the ultra sought after originals, now over 58 years years old! ... The real McCoy that everybody wants. These tubes test very strong & sound wonderful -- Guaranteed NO DOA. They'll provide the sound and excellent lifespan you can rely only on very old WECO triodes for. These are original production from 52nd & 39th week of 1953! As close of a match in production, construction & performance you're ever likely to see...so set like this is a rarity and as long as you own, they'll probably rise in value. Early 50's (single D getter) Western Electric tubes like this will outlast and outperform many newer triodes of similar design ... they were made to the highest standards ... and have a wonderfuly accurate sound quality with amazing resolution & musicality. You can really hear the legendary smoothness, yet very agile & dynamic. Carefully stored for years in original era Western Electric boxes (some stains on boxes from storage many years).
Both tubes sounded beautiful when played with music when tested in WE 91 single ended circuit & 5.2 volts filament. No noise, great function, in the single ended circuit. NO SHORTS, both checked perfect beyond 2 megohms in Jackson machine. ) Tests made in multiple calibrated testers, including a Calibrated TV/7 the world's standard for WE tubes.... BOTH are STRONG on GM (mutual conductance) (TV7 minimum is 58), (#1) 82 , (#2) 82 ... a perfect match!
For easy reference, see Exhibits (C & D). The pair reads about MATCHED at 110% on Jackson 648R at full load. They also score very well on the projected life. A test in which tubes are tested under reduced filament voltage. They thus have a good spacial charge.... retaining a good estimated life remaining!
Bases are tight. Tubes have been powered & used, for not very long ... as the still shinny flashing indicates. The clarity of glass is another indicator these had light duty & low hours (the TV7 / Jackson life test was good for both). . See photos. Both tubes have clear beautiful bottle tops....tight bases. All signs indicate these tubes have not been used much and have had a pretty easy life thus far. Both have about the same flashing, thick, shinny, but no darkness and absolutely no burns... Yellow letters perfect on both. These gorgeous bakelite bases are both sturdy - no cracks.
The original single side D getter arrangement (made late 40s to mid 1950s) 300B is getting quite scarce now. Since these tubes were produced during the same run -- they have the same getter design. They postdate & predate the more common ring or round halo design. They sound great & will sell very quickly. Vintage Western Electric's are the king of triode sound - you will hear enhanced clarity, great tone, agile pitch - all the while maintaining legendary smoothness. 1950s 300B's generally test stronger and produce even better quality audio than triodes of the later production. Collectors know originals are for the keeping and using!
This beautiful matched pair will sell very quickly. See our 100% feedback, to be assured SAFE PACKING & DELIVERY. These are likely the best original 300B with boxes .. and most throughly tested you'll see anywhere.
