Description

Single tube, not matched

JJ developed a completly new tube which is compatible with the EL84. The difference lies in the around 25% decreased headroom. This will give you the benefit to get the often desired power amp overdrive at lower volume levels. We recommend this tube for low wattage amps to get a better sound at bedroom levels.

Please check the datasheet!

WGS G12Q 12" / 20 W / 16 Ohm

Building on the popularity of our G12C, we developed the G12Q for those times when you want the speaker to add some natural, vintage breakup but maintain clarity. With a 20 oz magnet and a 1" voicecoil, the G12Q definitely has a vintage American flavor. We highly recommend it with 5E3 style circuits.

TT 12AX7 / ECC83 Classic V1

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

The TT12AX7 impresses with its fine and detailed reproduction of the highs, which is maintained even at high amplification levels. Due to a higher H3 part, the TT12AX7 sounds significantly cleaner than many other 12AX7/ECC83 tubes, which makes the bass range appear much tighter. We therefore especially recommend this tube for styles such as clean, crunch, and metal, where high amplification and clear transparency are required.

Application Notes

Heater operation: The tube can be operated with 6.3V or 12.6V, depending on the circuit design.
Grid resistors: It is recommended to use grid resistors of at least 1MΩ to ensure stable functionality.
Coupling capacitors: Capacitors with low capacitance (typically 0.1µF) are recommended to minimize high-frequency interference.
