Sovtek 12AX7 / ECC83 LPS

Very linear working 12AX7 / ECC83 with long anode plates and spiral heating, which makes the tube less sensitive to interference from AC heating.
We recommend this tube for audio and high-end amps as well as for "modern" Fender amps with more overdrive, but also as an input tube in old Marshall JCM800s.

Note: Tubes equipped with long plates are commonly associated with a "warmer" or "richer" sound, whereas those with shorter plates tend to deliver a "tighter sound". However, tubes featuring long plates exhibit increased sensitivity to vibrations and mechanical disturbances, rendering them less ideal for critical applications.

JJ 6V6 Red Labe - PAIR - Double Mica Special Edition

2 tubes, matched as pair

JJ 6V6 Double Mica double-layered mica in the upper part of the tube. This stabilizes the tube system and significantly reduces possible vibrations that can occur due to heavy mechanical stress. This version of the JJ 6V6 was specifically designed for use in combo amplifiers.

The JJ6V6 is a beam power pentode with octal base and a maximum plate dissipation of 14W. It has fat low end and full mid tones with very good tone separation and a smooth, clean high end - in general, a very balanced tone.
Currently, the only new production 6V6 which is approved for up to 500V anode voltage in pentode operation.

TT 12AX7 / ECC83 Classic

Tube-Town 12AX7 / ECC83 Preamp-Tube

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.

Kit Dumbleator

This is a kit of the famous Dumbleator, can be used as standalone device or for installation in an existing amplifier.

When build as a stand-alone device, the kit can be powered with the TT-VPump, in an amplifier the kit must be supplied via the existing power supply of the amp.

The Dumbleator offers numerous configuration options which are shown in the appended schematics.

Input Levels:
InA: 10-15 Vpp
InB: guitar level - 5 Vpp

The kit includes all the parts needed to build the "standard version" incl. a 12AX7, potentiometers and leads.
It does not include components that are required for the building the extended versions, as well as a power supply or casing.

The Dumbleator utilize POTENTIALLY FATAL HIGH VOLTAGES.
Seek help from a competent technician if you are in any way unfamiliar with high voltage circuits.
Use at your own risk.
