Sovtek 6C45PI single triode preamp tube. Made in Russia.
The 6C45P (6S45P in the western alphabet) is a high mu triode with a very high transconductance, incredible linearity, very low noise, and low plate resistance. This amazing tube will excel in small signal applications, as well as a driver, or anywhere really precise performance is required.
$53.55
Vacuum Tube - 6CA4, Electro-Harmonix
Electro-Harmonix 6CA4 full-wave rectifier tube. Made in Russia.
$27.95
Vacuum Tube - 6CA4 / EZ81, JJ Electronics
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
Vacuum Tube - 6CA4 / EZ81, Rectifier, Full Wave
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
Vacuum Tube - 6CA5 / 6EH5, Tetrode, Beam Power
Miniature beam power pentode designed for service as an audio output amplifier. It features high power sensitivity at relatively low plate and screen voltages.
$3.90
Vacuum Tube - 6CA7, Electro-Harmonix
Electro-Harmonix 6CA7 Vacuum Tube Big bottle beam-tetrode version of EL34. Perfect EL34 replacement for Musicman amplifiers.
Starting at $36.10
Vacuum Tube - 6CA7, JJ Electronics
A true to form reproduction of a classic tube that will work in most EL34 amps. The 6CA7 is often considered the American cousin to the British EL34. Sonically, this tube is closer to a 6L6 than an EL34 but without the sometimes harsh high end of the 6L6.
Starting at $25.50
Vacuum Tube - 6CB5A, Beam Power Amplifier
High perveance beam power pentode in a T-12 glass envelope. It is designed especially for use as a horizontal-deflection amplifier in color television receivers. The 6CB5A is unilaterally interchangeable with the 6CB5.
$29.90
Vacuum Tube - 6CB6A / 6CF6, Pentode, Sharp Cut-Off
Miniature pentode designed for use as a radio-frequency or intermediate-frequency amplifier in television receivers. Features of the tube include high transconductance and low interelectrode capacitances.
$3.90
Vacuum Tube - 6CD6GA / 6EX6, Tetrode, Beam Power
Beam-power pentode designed primarily for use as the horizontal deflection amplifier in television receivers which incorporate large deflection-angle picture tubes.
$6.90
Vacuum Tube - 6CD7 / EM34, Indicator, Tuning
