Potentiometer für Marshall JCM900, 1 MOhm Log

4 tubes, matched as quad

The Sovtek 5881 delivers a warm, round tone that "sweetens" any vintage or modern guitar amp design. Chances are if an amp uses 6L6-style output tubes, it has Sovtek 5881's in its sockets. Built to rigid military standards, the 5881 will tolerate higher voltages than any other 6L6. In fact, they're frequently used as replacements for the old 7027 model in vintage Ampegs.

• Bridge Rectifier
• Average Rectified Output Current Io (@TA = 50°C): 1,5A
• Forward Voltage Vfm(@IF = 1.5A): 1,0 V
• Peak reverse Voltage: 200 V

The Sovtek EL84 series produces an unbeatable smooth, warm distortion sound. Excellent replacements in vintage VOX AC-30's and the like, very popular in Fender, Crate and Peavey amps.

The 6L6WXT+ features larger plate dimensions and 20 percent higher output than the Sovtek 5881WXT. Extremely low noise and a excellent detailed and harmonic sound, plenty of power and very easy to handle - even while using in "hot" setups.

TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)

Sweet and warm sounding preamp tube with high gain. We recommend this tube for guitar/bass amps.

Mullard reincarnated. With the new EL34EH, Marshall amp owners can recreate the balanced tone, deep, tight bass, sweet mids, and well-defined highs of the original equipment Mullards. Innovative design and precision construction give the EL34EH exceptionally smooth and an ideal balance of pleasing even-order harmonics while virtually eliminating undesirable odd-order harmonics.

The Sovtek 12AX7WC has a little bit more gain than the Sovtek 12AX7WB and  the 12AX7WA. The noise floor is still pretty low compared with other 12AX7 tubes and the dependabiliyt very high.

TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)

The Sovtek 12AX7WA is a defacto standard in 12AX7 tubes for many years yet because of its high dependability and its low noise floor.
