for sale: pair of rare vintage Beckman 5963 tubes. Yellow Beckman logo. Made in USA. Tube construction is long grey plate, double mica, square getter. The 5963 is a premium industrial grade tube similar to the 12AU7 and equivalent to the European ECC82.Brent Jesse describes the 5963: "This is a nice industrial type which is nearly identical to the standard 12AU7. RCA made a nice blackplate version of this tube, Sylvania has a gold pin version, and GE has it in their 5-star broadcast line. The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine. It has a rugged cathode and should be long lived, similar to the 5814. Watch this tube, as it is plentiful now and prices are low. As audiophiles discover it, the rush will be on!" Tested strong (exact test result numbers not available) Guaranteed to work, but no particular test results are guaranteed. The lettering on one of the tubes is mostly worn off. Rated at 7 for worn lettering, non-original boxes and non-specfic test results. This is a low cost entry point to try out a pair of 5963s. $5 to package and mail in US. please contact me for shipping quote to other countries. Thanks for looking.
