Vacuum Tube - 6F6, Pentode, Power
Pentode amplifier designed for application in power output stages of receivers
$12.95 Vacuum Tube - 6SH7, Pentode, Sharp Cut-Off, RF Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.$4.90
Vacuum Tube - 12SJ7, Pentode, Sharp Cut-Off
A single-ended RF pentode having sharp cut-off characteristics. It is designed for use as a general purpose amplifier, biased detector, radio frequency oscillator or as a mixer tube in properly designed circuits.
$3.90 Vacuum Tube - 6CW5 / EL86, Pentode, Power Amplifier The 6CW5 is an A.F. output pentode in the 9 pin miniature construction. It is intended for use in single-ended push-pull output stages.$6.90
Vacuum Tube - 6CZ5, Tetrode, Beam Power
9 pin miniature type beam power tube. Its heater has a controlled warm-up time.
$13.90 Vacuum Tube - 6SN7GT, Classic Series, Psvane The Psvane 6SN7GT is a high quality, medium gain, dual triode with an octal base. The Psvane 6SN7GT is an excellent preamp tube with a classic look and sound. The Psvane 6SN7GT works great in any 6SN7 position. The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications. Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand.$24.45
Vacuum Tube - 6AW8A, Triode, Pentode
Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.
$4.90 Vacuum Tube - 5881, Tung-Sol Reissue Russian made reissue of the original Tungsol. The 5881 is the electrical equivalent to types 6L6 and 6L6G except that the plate and screen dissipation ratings have been increased approximately 20 percent. It embodies a complete mechanical redesign which results in greater resistance to shock and vibration. Starting at$38.95
Vacuum Tube - 5R4WGA-B-Y, Rectifier, Full Wave
Long life, ruggedized, reliable full wave rectifier tube.
$11.95 Vacuum Tube - 6H6, Diode, Twin Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier$4.90
Vacuum Tube - 6K7, Pentode, Remote Cut-Off
Variable mu pentode amplifier in the octal metal (glass) construction. It is suitable for use with AVC in RF and IF amplifiers and minimizes cross modulation.
$6.90 Vacuum Tube - 7868, Electro-Harmonix Electro-Harmonix 7868 power pentode tube with a magnoval style base. Made in Russia. Starting at$52.70
Vacuum Tube - 7C5, Tetrode, Beam Power
Beam power amplifier tetrode designed for service in the output stage of a-c or battery-operated equipment. It is capable of supplying high-power output, power sensitivity, and efficiency with low percentages of third and higher order harmonics.
$9.90 Vacuum Tube - KT66, Tube Amp Doctor, Premium Selected The Tube Amp Doctor KT-66 is an incredible remake of the classic British tube. With its large glass envelope contoured by smooth curves tapering into a rounded brown base, the TAD KT-66 not only looks like the original, it performs like the original. This KT66 offers plenty of headroom for a thick full bodied sound with smooth yet articulate highs. The KT-66 is famously used in vintage British plexi amps and makes a great replacement for that style of amplifier and many others. The TAD KT66 is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process. The TAD KT-66 can be used in any KT-66 position as well as 6L6GC and 5881 amps that can supply the required 1.27A for the heater. Starting at$56.95
