RCA 5693 "Special Red" Tubes
Reviews Qty: (0)
Unfortunately this item is no longer available.
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.

What does "NOS" mean, anyway?:
Commonly known as "NOS," the term New Old Stock simply refers to tubes that were made years ago but have never been used. Much like antiques, "NOS" tubes are currently not being manufactured and this means their supply is dwindling while the price continues to rise.
For most NOS tubes we have a variety of brands available. Typically these are the common brands such as RCA, Sylvania, GE, Raytheon, etc. However, there are instances where lesser known brands are in stock. If you have a particular brand you prefer you can simply request it in the Order Comment box when you place your order.
