- Tube Type: 6L6/5881
The russian 5881 was born as 6P3S-E in the Saratov plant and was designed for the use in military vehicles and aircrafts.
Outstanding mechanical sturdyness and reliability is its key feature.
Today this tube is mostly known as Sovtek / Russia brand 5881 / 6L6WGC which is the current production version of the identical tube.
The original military 6P3S-E tube was made to the highest standards with tights limits in quality spread.
Consequently we try to provide you with this original mil. grade 6P3S-E / Sov. if possible.
Please note that the marking on the original tube says 6P3S-E while the Sovtek says "5881 / 6L6WGC".
In case we can not get the NOS 6P3S-E we do provide the Sovtek branded item instead.
NOTE: the MESA Boogie STR-425 is the same make as this tube. If you order for your Boogie (matched pairs and quads only) then please remark the required Boogie colour code in the order comment during check-out.
| These are the gold pin version of the standard ECC83. These tubes are immediately discerni-ble from other 12AX7. They have a construction that is similar to a frame-grid tube - similar to the Telefunken ECC803s. This construction makes them very rugged and reliable. This is one of the best new 12AX7 for any guitar amp. It is very musical - rich with great harmonics. An excellent tube in all Marshall amps in the three preamp positions.
Factory selected tubes with gold pins. These tubes provide high gain without the usual noise and microphonic problems you would expect. This is great sound and value for your money.
ECC83S is 12AX7 high gain pre-amplifying double triode. Thanks to its design it also peforms with very low noise and microphonics. Harmonically rich, with a detailed low end and a warm high end.
12AX7/ECC83/7025 / 9Pin Socket Noval | The TAD JJ EL34 Quartett Matched Tubes
The JJ Electronic EL34 is another classic from JJ.
This tube features a rugged construction leading to an incredibly reliable EL34 with astonishing tone.
Overall the sound is nicely balanced with tight lows, a rich and dynamic mid range and clear highs.
The JJ EL34 is a great replacement for guitar amplifiers and stereo amps.
Base: OCTAL
uf = 6,3 V
I f = 1,5 a
Typical Characteristics:
ua = 250 V
ug3 = 0 V
ug2 = 265 V
ug1 = from -10 to -13,5 V
(for eL34)
from -13,5 to -16,5 V V
(for e34L)
I a = 100 ma
I g2 = 14,9 ma
S = 11 ma/V
R i = 15 kΩ
μ g2/g1 = 11
Limiting Values:
ua0 = 2000 V
ua = 800 V
W a(max) = 25 W
ug20 = 800 V
ug2 = 450 V
W g2(max) = 8 W
I k = 150 ma
uk/f = 100 V
R k/f = 20 kΩ
Capacitances:
c g1 = 15,5 pf
c a = 10 pf
c a/g1 = 1,3 pf | 5751 can be used in most 12AX7 circuits to achieve more headroom.
It has a lower gain about 70% than the standard 12AX7. Good to rope the gain of a high gain amplifier.

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.

| 6L6GC-STR Redbase TAD PREMIUM Selected
The Classic 6L6 Sound - Excellent Tone and Maximum Lifetime!
The TAD 6L6GCM-STR REDBASE is a latest 6L6GC designed and built to claim to be the best 6L6 type tube ever manufactured.
A damn high claim, but we are sure that we have achieved exactly that.
In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs. In every setting, the TAD 6L6GCM-STR REDBASE responds directly and with noticeable dynamics, from buttery soft and warm to powerful and brutal without losing any details or depth.
This makes the TAD 6L6GCM-STR an effective upgrade for every amplifier using 6L6GC or 5881 tubes; also repalces any EL37, CV586, VT115A, 6L6GA, 6L6GB, 6L6WGB, 6L6WGC, STR-440, STR-454, 6p3p, 6p3s, 6p3s-e etc.
The TAD 6L6GCM-STR REDBASE combines the structural advantages of the robust American Philips / Sylvania 6L6GC, also known as MESA 6L6GC-STR415, and the sound quality of the legendary RCA 6L6GC tubes.
Silky highs, defined, deep bass and lots of headroom recommend the TAD 6L6GCM-STR REDBASE for lively clean sounds as well as a powerful broadband power amplifier for multi-channel amps.
