Vacuum Tubes
The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
The 5Z4 is designed for service as a power rectifier in AC operated receivers.
$8.90
Full-wave high-vacuum rectifier for use in power supplies of moderate current requirements. The tube incorporates a unipotential cathode which is internally connected to the filament.
$49.90
Miniature full-wave high-vacuum rectifier intended for use in power supplies which have low d-c output-current requirements.
$11.90
Full-wave rectifier of the heater-cathode type intended for use in AC operated and automobile receivers. Because of its heater-cathode construction it has the same heating time as that of other heater-cathode types in the receiver.
$5.90
Isa full-wave high-vacuum rectifier designed for damper service in television deflection circuits. It can also be used in conventional rectifier applications.
$11.90
Electro-Harmonix 6CA4 full-wave rectifier tube. Made in Russia.
$27.95
The JJ Electronic EZ81 is a noval based rectifier with a rugged construction. These tubes are an excellent choice for guitar amps such as 18W Marshalls and Hi-Fi amplifiers as well. This tube will work in any EZ81 or 6CA4 application.
$17.95
Miniature, heater-cathode, twin diode for full-wave rectifier operation. High output current and small size make it especially suitable for compact amplifier designs.
$24.90
New Old Stock 6W5-G. Full-wave high-vacuum rectifier.
$19.95
Miniature heater-cathode type twin diode designed for full-wave rectifier operation in compact power supplies. The tube is intended for service in automobile and a-c radio receivers.
$12.95
The 6X5G is an indirectly heated full-wave rectifiers for use in equipment where the current drain does not exceed 70 mA.
$14.80
Out of Stock
Cathode type rectifier designed particularly for use in automobile receivers.
$12.90
Heater type vacuum twin diode using the lock-in construction. It is intended for use as a full-wave rectifier in either AC or storage operated equipment where economy of heater power is desired.
$3.90
Heater-cathode type high vacuum twin diode using the lock in construction. It is intended for power rectifier service in AC operated equipment or for use with storage battery and vibrator in automotive receivers or amplifiers.
$4.90
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
Starting at $17.60
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
$29.90
Half-wave high-vacuum rectifier which may be used with either choke or condenser input to the filter.
$27.35
Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents
$25.60
High vacuum full wave rectifying tube.

Originally: $12.90
Premium directly heated heavy duty rectifier Diode. Re-issue of the most popular rectifier valve ever built by Mullard. Helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied.
- Low internal voltage drop & controlled heater warm up time
- Excellent choice for both Hifi and instrument amplification
- Replacement/upgrade for all 5AR4/GZ34 types
