Octal power tube (Max Plate Watts = 30W) TAD 6L6GC-STR RCA-Style black-plate

TAD has the remakes of the all time favorite 6L6 classics by RCA and GE. The TAD 6L6GC-STR is your perfect choice if you are up for the sound of the rock legends. It provides the low end with the right amount of pressure, as known from the famous RCA tubes. It has clear, transparent but unobstrusive highs and exactly the right bite to provide you with all those classic 6L6 sounds from big warm cleans to modern hard rock sounds.

This TAD 6L6GC-STR combines the famous reliability of the american made Philips/Sylvania STR series (also known as MESA 6L6GC-STR415) with the black-plate system of the highly regarded vintage RCA 6L6GC tubes. Silky top end, combined with deep bass response and lots of headroom make this tube a living classic.

Exclusive black-plate designs, gold gird wire, double getter construction, no-noise filaments and the 1.2mm thick heavy duty glass envelope.

Do these have that woody RCA carbon black plate coating sound? NO! They sound more like a gray plate but they do sound pretty nice. These are a Chinese made tube, made in China, and China just seems to keep improving on the sound and the reliability. The longevity is still lacking, but noone wants to pay $90 for 12AX7 that will last for 20 years or $240 for a 6L6GC that will last for 25 or 30 years of hard use, so we are stuck with "this" instead. These are also not very good in amps with high plate voltages so I wind up designing amps with a lower B+ and higher current, to get less wattage and somewhat better headroom, and better reliability. If I was comparing these to actual RCAs they would maybe get 2 stars.

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!

regards

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.
