Vacuum Tubes

"Svetlana tubes are quite simply the absolute best. We design and manufacture our tubes, engineered for demanding high fidelity, reliability and overall warmth."

High-mu twin triode designed primarily for use as an AF voltage amplifier. Featuring a special shielding arrangement to reduce hum, the tube is well suited for low-level audio amplifier service.

The 6V6 is a low-output power tube (12-18 watts) often used in Fender® amplifiers, including the Champ®, Deluxe™, Dual Professional, Vibro-King®, Princeton®, Vibrolux® and others. It has a very warm, round and soft response with rich harmonics, and distorts easily. One of the best choices ever produced for rehearsal and recording amplifiers. Our most premium design, for long life and professional performance. The choice for many pro players who use Groove Tubes in their favorite amps for recording and rehearsal; fully captures the spirit and sound of tube amps from the '50s and '60s to the present.

New Old Stock 6W5-G. Full-wave high-vacuum rectifier.

Special quality double triode designed for use as cascode amplifier, cathode follower, etc. in RF and AF circuits.

Glass octal beam power pentode designed for use as an audio frequency power output tube. The tube has a high power sensitivity and high efficiency and is especially designed for applications where high power output is required.

Transmitting triode

Half-wave high-vacuum rectifier which may be used with either choke or condenser input to the filter.

Special quality pentode designed for use as a wide band output tube.

Transmitting triode for operation at maximum ratings up to 250 Mc.

The 841 is an RF power amplifier, oscillator, and AF voltage amplifier.

Beam-power pentode intended for service in high power, high-fidelity audio equipments and is capable of 100 watts output in push-pull circuitry. It also finds application as a regulator tube.

Compactron beam power pentode primarily designed for RF power output applications. Features of the 8950 are dual cathode and grid connections for lower lead inductance, and a 13 volt heater.

New Old-Stock (N.O.S.) tube. The 930 is a gas phototube sensitive to red through infrared light.

Groove Tube's Gold Series EL84. The warmest Groove Tube in this family. It remains very buttery, with relatively high power output and very even response. A great replacement for many modern stock amps, overcoming a variety of design issues and limitations in inexpensive tube amps.
