Octal power tube (Max Plate Watts = 30W) TAD 6L6GC-STR RCA-Style black-plate "TAD has the remakes of the all times favorite 6L6 classics of RCA and GE. The TAD 6L6GC-STR is the perfect choice for the tone of the rock legends with powerful deep bass and clear but pleasing airy top end. The new 6L6GC-STR forwards the low end with pressure and has all the guts and bite to perfectly accomplish all the rocking sounds from R'n'R like SRV to modern NU-Metal and they live and breathe. This TAD 6L6GC-STR combines the famous reliability of the American made Philips/Sylvania STR series plus the our beefed-up black-plate system like the highly regarded vintage RCA 6L6GC tubes. We joined best of both worlds! Silky top end combined with deep bass response and lots of headroom make this tube a living classic. The TAD 6L6GC-STR and the TAD 6L6WGC-STR have our exclusive black-plate designs, gold gird wire, double getter construction, no-noise filaments and 1.2mm thick heavy duty glass envelope. Along with the TAD 6L6WGC-STR (GE-Style) is this TAD 6L6GC-STR our recommendation for excellent tone and maximum lifetime among the 6L6GC type tubes." -Tube Amp Doctor

Great sounding, functioning 6L6GC-STR reproduction...Although those were never "RCA" tubes, they were made by Sylvania. RCA and many other brands were applied to those tubes, but all of the tall bottle 6L6GC-STR tubes,. of which this is a pretty god copy, were actually produced at the Sylvania plant.

thanks for replacing the bad tube! great service and understanding the situation...
good quality tube but poor quality base on TAD products;

from my original order: one of the TAD 6L6GC base keys broke and in the process fractured the tube while installing in well worn in, 39 year old socket of a Fender Super Six Reverb amp. ... which i sent back and you replaced thanks!...

On the same amp different socket upon doing a bias setup with the other TADS i bought in the original order, a 6L6WGC had a similar issue where the key broke but fortunately the tube glass did not fracture and i was able to super glue the key back on....

so end result i refuse to buy TAD products in the future as there tubes may be nice and they do sound nice in the amp considering the failure i can't afford to have this crap in my working amp as i travel as who knows when the next mechanical failure may occur!
TAD's molding process is definitely inferior and to pay a premium for crap is rediculous!! the tubes are worth no more than 10$ a piece in my opinion....

so thank you for your exception business and understanding as ni don't think its a reflection on you as a company but from now on its JJs or else but no way TAD... ps if i was in quality control for antique electronics i would cancel TAD's contract effective immediately as this is not the first or last time you will hear of this issue!

TAD 6L6GC-STR. These came as OEM in my new Richter RS-33 tweed Bassman inspired combo. As an old (literally) 6L6 user, these are among the nicest sounding tubes I've ever used, and at the top of those currently produced. I wound up using these new ones as spares or replacement (should I out live my current OEM's from Sara), and I was able to continue using my current set, also from Richter, and from you as her OEM supplier, by purchasing your handy key inserts. The buying experience was top-notch as well. Thank you!

Received the tubes in perfect condition. They were replacing Silvertone/RCA Black plates so had quite the shoes to fill......perfect. Thank you!

The new tubes make my 37 year old amp sing. The order was placed, processed and delivered with no hassle at all. I will definitely be a return customer.
