Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
Starting at $17.60
Vacuum Tube - 12AT7 / ECC81, Triode, Dual, HI-MU
The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
Vacuum Tube - 12AZ7A, Triode, Dual
9-pin miniature type high-mu twin triode, with heater having controlled warm-up time.
Vacuum Tube - 6SN7, Electro-Harmonix
Electro-Harmonix 6SN7 medium-mu twin triode preamp tube. Made in Russia. New low noise HiFi 6SN7.
Vacuum Tube - 12AX7-A, Triode, Dual, High MU
Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.
Vacuum Tube - 13EM7 / 15EA7, Triode, Dissimilar Double
Dissimilar double-triode designed for use as a combined vertical deflection oscillator and amplifier in television receivers
Vacuum Tube - 5Y3GT, Rectifier, Full Wave
Filamentary twin-diode designed for full-wave rectifier operation in power supplies that have d-c output current requirements up to approximately 125 milliamperes.
Vacuum Tube - 6100 / 6C4WA, Triode, Medium-MU
The 6100 / 6C4WA is a heater-cathode type medium-mu triode of miniature construction, suitable for use as a class C amplifier and oscillator. This type is characterized by long life and stable performance.
Vacuum Tube - 12AT7, Groove Tubes
9 pin miniature preamp tube (Amplification Factor = 60)
Durable phase splitter or driver tube. Excellent in vibrato or reverb circuits where consistent, high output power is desired.
