Manufactured by Tung Sol, labeled and boxed as GE. Great in your tweed Bassman and other Fenders and boutique amps that require 5881s.
Mike, 3 more matched pairs of the Tung Sol 5881 "Christmas Specials" (RCA label). The three pairs that you sent prior were really excellent specimens visually and sonically. Thanks. John
NOS in original boxes. Labeled and boxed as National 6L6WGB.
"Coke bottle" shape. NOS in original and white boxes. Some labeled as National 6L6WGB. Good for 5881 and 6L6 applications where plate voltage is under 450V.
BEST PRICE ON THE WEB! These work great in old Fenders requiring 5881's or 6L6's. Good substitute in 6L6GC amps where less headroom (breakup at lower volumes) is desired. Also make great replacements in Fender Deluxe's where more clean headroom is desired. Just plug into your Deluxe and re-bias, no circuit changes required. Excellent choice for most 6L6GC amps if you'd like a little less clean headroom. These hold up well in amps with plate voltage up to 470 volts.
