Replaces 5693, 6SJ7, and 6SJ7GT tube types. The RCA "Special Red" tubes (5690, 5691, 5692, 5693) were designed for 10,000 hours of use. RCA claimed the 5693 tube could withstand shocks of 100 G's for extended periods of time! These should be considered a top pick for old amps like Gibson, Danelectro, and any other vintage amp requiring a 6SJ7 tube. Assorted brands in stock but all red tubes were produced by RCA regardless of branding. Availability: Out of stock. Return to 0000 to 9999 Tube Types |
