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.

| 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.
