Rare find! All matched set ... nice early -- from the pre-war silver era...built in the true fit and finish of 1930's WECO both from mid 1942 (matched year date codes) ... genuine, more than 70 years old. They are paper wax capacitors from Western Electric tube long lines preamplifier audio equipment, the Bell System and ERPI cinema sound --- absolutely beautiful letters and shinny original silver paint, with a few nicks and chips from the many years, they look, test and the feels nearly like new (see Exhibit A,C,D,E) so very old and rare these days! This is a matched in capacity & tested (no leaks see reports in Exhibit A. Study exhibit (B) to see an actual unit(s) and under HV & ESR test (no leaks), both units test perfectly.
Great looking, NICE paint with only a few flaws from the 60 + years of storage (see exhibit B,C,D,E), Perfect for amplifiers, preamplifiers and crossovers (as a tweeter high pass, where they are ideally suited) . They have tested at real world operating 200 volts DC on Sencore tester. The pair, WORKING great , thoroughly checked out and found to be PERFECT - no leaks, low ESR, and verified 1uf capacity !
See reports (Exhibit B,C,D,E). These have thick copper-clad wire wrap terminal lugs set in bakelite. They type used in MirroPhonic era and OK for FM 1930s and 1940s recording / playback and from there, well into the early 1950s -- some of the finest sounding and now most collectible audio for HiFi uses. The 141(X) series spanned a multitude of capacitance values, for many uses. The carefully handcrafted slimline steel / bakeliite construction appeared on the scene to replace the 8x series, that had been produced sinece the late 1890s by Western Electric. By the early 1930's WEC redesigned their caps for newer higher voltage surges, longer reliability, and far better compactness. These were the earliest era of topside, studded for chassis mount -- and were widely used in MirroPhonic era audio -- as it was perfectly compact for topmount onto triode / pentode audio amps and preamps. The new slimmer, smaller case was at first silver (as these) which replaced the 89 series of the Black laquer paper wax caps that had been broadly used across the Bell System for many years before.
Tube amp and crossover builders DiY builders are tirelessly seeking these -- Western Electric paper in oil caps have long been very sought after -- because they have long life and higher voltage ratings, and most important... they sound wonderful. More expensive sealed oil types are good too if you need the heft and higher continuous voltage. For many years, audiophiles and astute builders have known that paper / wax Western Electric caps of this era sound better in their intended voltage range (most WE paper caps were intended to HiPot in the 500V DC range for brief periods, and 200V-250V for DC cont duty) -- and especially for use in speaker systems -- as high pass crossover implemtation. Paper wax caps are well known to sound stellar in audio ( a few boutique companies are once again producing disposible 1950s types). Nothing compares to the heavy build of 1930's-40s Western Electric!
These very early caps sound wonderful, pefect for all vintage and modern audio projects. These are the real thing, with all the legendary quality and durability of genuine Western Electric --- they may outlast our children. These are some of the last units to be found in the USA -- from unused, low hrs and (some NOS),Bell System tube audio equipment. Stored carefully for many years. Very rare now and you won't see again and you cannot find them elsewhere in such throughly tested and nice tested condition.
These are very rare nowadays. This pair will sell very quickly within hours. Buy now to avoid a bidder's war.
Useful in many ways for your vintage audio projects...and the original WECO sound. Cherished by audio builders all over the world. Excellent for crossover / speaker projects where audio quality is crucial. Very difficult to find in Nice Condition and completely tested. Includes original type brass mounting hardware (see exhibit E).
