Up for sale, I have a closely matched pair of genuine vintage 1960s RCA 5U4GB Black Plate octal rectifiers. These tubes are superb sounding, highly desirable, and are known for their extra-long life and high reliability. If you’re reading this, you already know that these sound much better and are way more reliable than the modern Chinese or Russian rectifiers. There’s a very good reason why many people feel that RCAs are the best.
I have been doing a great deal of tube rolling lately, and have decided to sell these great tubes off (I only used them for about 15-20 hours after purchasing them), as I just have too many tubes accumulating. This is your chance to pick up a pair of these beauties at a great price.
These tubes sell for $99 each from the TubeDepot. I am only asking $32.50 for the pair plus $7.50 towards the shipping, and I’ll cover PayPal fees and the remainder of UPS shipping to any of the lower 48 states. Rated as 7 due solely to age. Only 1 tube still has orange writing on base, but tubes appear identical and both came in the original RCA boxes when I bought them. Check my feedback and buy with confidence. Thanks for looking!
