Product information "EL84-STR REDBASE TAD PREMIUM Matched"

The all new TAD-EL84-STR REDBASE brings together the best of both - the famous EL84-Cz and the EL84M. We opted for the thickest glass possible and the heaviest construction available, just like the Russian EL84M, and combined these features with the sonically most promising cathode plate options, in order to meet and exceed the tonal quality of the EL84-Cz especially with regard to its linearity over the entire frequency range. Finally we added the gold grid wire in order to improve overall reliability. The sound can be described as very harmonic in the middle and treble frequencies, without adding too much power to the bass. The result is the best EL84 in current production.

No Compromise!

note:

Due to its diameter of 22.5mm, the TAD EL84-STR does not fit into older Marshall DSL401 made till week #20 in 2014 and UK made VOX AC15 TBX amplifiers of the same time range.

The tube which did fit these amps is the Ei EL84 or certain NOS models. All new production of EL84 do use the 22.5mm standard.

Later versions of these amplifiers have been updated to accept 22.5mm diameter tubes with no problem.

Tube Type:	EL84/6BQ5/6P14P/N709
Socket:	9 Pin(Noval)
Selection:	Premium

Customer evaluation for "EL84-STR REDBASE TAD PREMIUM Matched"

From: Chris On: 8 Dec 2015

use them in a small Fender amp and they will give you a warmer and nicely detailed sound. after 4 months there is no rattling like the stock tubes did after 3 weeks. The original Fender spares I tried at first turned noisy after a few weeks as well. But these TAD EL84 stay quiet!

The have good bottom but overemphasized; they have warm and strong mids but not too punchy.

I really like 'em and would recommned them by this experience with small amps; especially 15 W Pro Junior type Fender combos.

From: František On: 19 Feb 2014

I put them into my Pro JR with greenback speaker.

Really nice warm and articulate clean sound...It makes little "twin" from Pro JR....

From: David On: 27 Aug 2012

They're great all rounders!

From: Eric Beucler On: 18 Apr 2011

I really like their punch and their bass response

From: Jaime Collier On: 12 Nov 2009

Really good el 84 for metal and modern rock sounds it has a full range with good bass response sounds pretty much unlike most el84 types out there i have jj; mullard; amperex and all sorts of nos types to compare it to and I say this tube is a winner for different sounding good tone than what you would expect from an el84

Information about TAD Matching

Here you will find the most important information about the matching of our tubes

When does a tube become a Premium Selected tube?

Power tubes

All power tubes labeled Premium Selected have passed the following tests:

- Plate Current (PC) and Amplification (TC)

- Low Noise Test

- Microphonic Test

- Sonic Tests

- Shock Tests

- Listening Tests

- Shorts & Leakage Tests

Premium RT-Matching of Power Tubes

Our Premium Matching is an exact matching of power tubes with identical Plate Current (PC) and Transconductance (TC).

TAD Premium Selected tubes are guaranteed for a period of 6 months (according to terms of warranties)

for the quality criteria mentioned above.

Preamp tubes

All preamp tubes labeled Premium Selected have passed the following tests:

- Low Noise Test

- Microphonic Test

- Gain Test

- Sonic Tests

- Shock Tests

- Listening Tests

- Balanced Output Test

Premium Selected

We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.

For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection

HIGHGRADE SELECTION

But only those tubes which pass these tests best are labeled Highgrades.Typically this is approx. 3-10% from a production batch that qualifies for the HIGHGRADE rating from TAD.

Due to the very high selection requirements, this article is temporarily only available to a limited extent! Please note our shop-information on availability.

Matching and Selecting Options for Preamp Tubes

Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.

This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.

TAD Premium Selected/Highgrade tubes are guaranteed for a period of 6 months (according to terms of warranties)

for the quality criteria mentioned above.
