The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel.

0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.

Voltage Regulator, Diode, Glow-Discharge type.

The 0B2 is a two-electrode, inert-gas-filled cold cathode miniature tube intended for use as a voltage regulator.

The 0C2 is a cold cathode, gas-filled diode of miniature construction designed for use as a voltage regulator.

The 0C3-A is a two-element gas filled, cold cathode voltage regulator. It is designed to provide a regulated output of approximately 105 volts.

The 0D3-A is a two-element gas filled, cold cathode voltage regulator. It is designed to provide a regulated output of approximately 150 volts.

Beam power tube of the 9-pin miniature type designed for use as the output amplifier in automobile radio receivers operating from a 12-volt storage battery. The 12AB5 can provide high power output.

Electro-Harmonix 12AT7 / ECC81 Vacuum Tube Large plate format, superior dissipation over the originals. Perfect for reverb and driver circuits.

A good choice for phase inverters, reverb drivers, and general preamp use. This tube offers low noise, low microphonics, and warm smooth tones at a great price. Like all JJ tubes, it has a rugged construction that doesn’t compromise the sound of your amp. The JJ 12AT7 is a solid replacement for any 12AT7, ECC81, or 6201 tube. It can also be used to replace 12AX7 tubes in position 1 to reduce gain.
