EL84M TAD-Tubes, Premium Matched

Your 1st Choice When Dependability is Your Major Goal!

The TAD EL84M offers strong mids and defined bass response. Even, when played at lower volume or in a complex stage sound situation, your sound will prevail. This is the most reliable and longest-lasting military grade EL84 on the market and operates up to 10,000 hours. Unfortunately, this tube is not being produced anymore.
Grab them, while they last!

d= 22,5mm

Due to its diameter of 22.5mm, the TAD EL84-M does not fit into older Marshall DSL401 and UK made VOX AC15 TBX amplifiers. The only tube which fits these amps is the EL84-EI. (ordering number: NN471)

I own modified AC15 with Alnico Blue speaker. I found the EL84M simply great. Only they need to be biased right. Compare to most of others EL84s I should to boost the bias much hotter. With a cold bias the sound is sterile and dull. I got the original datasheet of Russian 6P14P-EB ( EL84M in TAD ) and the min. bias for class A is 40mA - typicaly 48mA !!! I have now 43mA.The Tubes are singin and sparkling - very lively sound. No hum, no harsh, no hiss.. I tried many others EL84s ( GT, JJ, Mesa Boogie, Engl ) and EL84M are the best.


It's a bless when you have an small combo that goes microphonic with any other EL84 but, sonically, has a very sterile tone.

These matching valves where the bizz, I bought five valves in all these for the power amp gives it a sweet sound thank you TAD for prompt service and delivery.

I will recommend you to friends and fellow musicians.

Thank you.
