Seller Notes:

“ a well cared for WE 300B from the early 1960, features the postwar style double D getter, one of the first ones that did. TV7 Tested at 86 (min 58 TV7) and 105% emission. This tube has a fair (acceptable) projected life. This  tube was used Class A, for a while, which left several visible streaks along the top of the tube -- normal for it's age and use pattern, as well as just a very small, amount of carbon dust from the manufacture (very faint, nearly impossible to see). This tube still has a very nice amount of flashing (see Exhibit G). This tube was carefully stored, as a spare for many years, and is working perfectly well (will be posting test video demonstration, see below). This tube had good performance, when tested in WE91 single ended amp, it sounded terrific, just as you would expect a 300B to.  (See test reports Exhibit B,C,D,E). The base yellow ink is very nice and quite legible, with nice letters. The bakelite base is solid, tight and free of cracks. This tube presents nicely, with very clear glass (other than bown marks at top), no rattles and  a tight base. Guaranteed working on arrival, no DOA.

A well cared for WE 300B --  very early, double D style from November 1960.

 This tube was carefully tested on a calibrated TV7, reading  86 (where a min=58 TV7, which is 65%)  and 105% emission, no shorts and fair projected life, on a calibrated Jackson 648 (where the min=70%).

This  tube was used at full power, Class A for a while, which imparted some minor brown streaks, normal for a tube of it's age and use pattern, and a very, very small amount of carbod dust left over from it's original manufacture (normal), otherwise the glass envelope is clear and healthly looking with very nice looking flashing along bottom (see exhibt G).

This gem was carefully stored, as a spare for many years, by an audiophile as backup, and is still working perfectly well (will be posting test video demonstration, see below). This tube had good performance, when tested in WE91 single ended amp, it sounded just terrific!  Just as you would expect an early 300B to -- audiophiles seek these, the post war, "double D getter" because they are built so well, they featured the most uniform construction and consistant quality -- and extended lifespan -- after the WWII round getter's.

  (See test reports Exhibit B,C,D,E). The base yellow ink is very nice, complete, and very legible. As you can see from photos, it presents nicely, with very clear glass (other than the normal browning at top) , no rattles and  a tight base. 

  This is an ultra sought after original, 55 years old! ... This nice tube is the real McCoy that everybody wants.

 Guaranteed NO DOA.  A real 300B can provide the detail and tone you can rely only on very old WECO triodes for.  Original production...

This tube sounded beautiful when played with music when tested in WE 91 single ended circuit at 5.2 volts filament.  Very good 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.... GM (mutual conductance) (TV7 minimum is 58 which is 65%) -- this tube read 86. 

For easy reference, see Exhibits (B,C). This tube read 105% on Jackson 648R at full load.  This is a used tube, scoring a fair (acceptable) projected life. A test in which tubes are tested under reduced filament voltage.

The original  era of the O getter arrangement (begininng in the engraved base 1930s,  until the mid 1940s, when WE abruptly sswitched to 1x lower "D" shape, which remained until the 1960s. The "double" D getter, as this tube features is known to many audiophiles to be an excellent era -- where super nice detailed sound is expected.

Early 300B's are getting quite scarce now. This is one of the best sounding postwar 50s-60s era 300B's to own. 

    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 tube 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.  They  come with original type WECO  cotton excelsior and boxes -- will be TRIPLE BOXED in strong 275lb triwall cartons.

Please study photos below. SAFE PURCHASE, 100% - *** Domestic or OVERSEAS OK. FAST SHIPPING, WILL DISPATCH IMMEDIATELY after PAYMENT -- OVERSEAS OK, FULL TRACKING number via email after shipment.

Guaranteed working on arrival, no DOA.
