4 tubes, matched as quad

The Svetlana 6550 is a high-quality beam tetrode for use in powerful tube amplifiers. It impresses with high resilience, stable operating points, and a balanced, powerful reproduction with tight bass, clear highs, and solid mids. Thanks to its robust mechanical construction, the tube operates with low vibration and reliability - ideal for both stage applications and demanding hi-fi setups.

The TT VPUMP kit is a very effective working voltage converter which generates an output voltage of 90 V DC to 220 V DC  from a 12V DC input voltage.
The circuit is in use for many years now and it is proven. In this kit the circuit has been adapted to a compact size and optimized for use in small preamplifier chassis. So it is an ideal HV power supply for tube stompboxes and preamps without the need of additional transformers and HV filter capacitors.

The VPump can be operated with a standard 12V DC switching power supply.
The switching power supply is not included in the kit.

Specification:
Input Voltage: 12 V DC @ min 4 VA
Output Voltage: 90 - 220 V DC, adjustable
Output Current: 15 mA @ 220 V DC max

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.
