These were removed from WORKING, often NOS Western Electric / Bell System tube amplifiers and long-life power supplies. They were specially made long life electrolytics, similar to those used in 1950s Marantz tube amps, like the Model 2 and Model 8/8B.
Western Electric used these because the reliability, quality and performance were by far the best in power supplies. Original grey finish with heavy duty bakelite tops with threaded inserts for easy chassis mount. The industrial grade threaded bakelite end plates make it easy to professionally mount to any build. Vintage, NOS real brass screws are included to complete the set.
These painted grades of electrolytics were best, in fact the APEX of USA built alumalytic type caps. Reform to full capacity when properly reformed by slowly raising voltage over a period of time, usually 10min to 1hour. The caps are low hours or NOS.
Because they have not been used for overy 40 years -- they will need to be reformed before use --like all vintage electrolytics, on occasion they may not... See example photo -- This 50+ year old cap easily reformed to full performance (open eye=no leak) (this one took about 50mins to reach peak operating after sitting years -- after which it's reformed and normal operation resumes)... This after many decades out of service. Here it is showing no major leakage at full operating DC 400V.
These caps will prove useful for many Diy and restoration projects -- anywhere you want the original type of electrolytic cap -- original parts are a perennial favorite of preamp and amplifier builders all over the world. The use of these reach far back to the early 1950s and Western Electrics best era of broadcast and recording amps like the OK for FM era. Many of the internal Bell Systems preamps, long line amps and recording equipment often used these for filter caps in the early days. Will be packed in extra strong, with lots of cushion, triple boxed to assure safe arrival.
