Tube Fender Groove Tubes GT 12AX7-R Slightly lower gain, quicker compression than GT 12AX7-R. Great for most Fenders, may not be well suited for high gain Fender type amps (such as Boogie). | Electro Harmonix EH6V6GT-MP Octal power tube (Max Plate Watts = 14W) Beam power tetrode with a specially developed cathode coating, careful alignment of the grid, tri-alloy plate material for flawless performance up to 475 volts. Perfect for high plate voltage amplifiers like the Fender Deluxe Reverb. This tube is perfect for guitar amps - it can take the abuse. Tube Type 6V6/6P6P-J/CV509/CV-511 Socket: Octal(8pin) |
Selected ECC83 for the big & warm clean sounds (great for HiFi too!) and mellow top-end when pushed to overdrive. Our recommendation if you want to emphasize punchy mids. Especially great when pushed into a fat overdrive.
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
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.

Some claim the 6L6EH has been "Modeled after the vintage RCA 6L6GC "blackplate" and the 6L6EH features large plate dimensions".
To see what a real blackplate looks like see the picture on the right showing a RCA and a TAD blackplate small bottle 6L6.
Both are real black plate constructions and great for vintage guitar amps for pleasing smooth and fine complex tone structure. Best for any classic Fender Amplifier.
The 6L6EH is a very good choice for more modern hard rocking guitar sounds and recommened for this.
