Electro-Harmonix 6AQ8 dual triode preamp tube. Made in Russia.

Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.

Russian-made Mullard Reissue 12AX7 dual triode. Large sound stage with excellent detail. Factory selected for low noise and microphonics. Great for hi-fi amps.

Rugged full-wave filamentary type rectifier designed for use in applications requiring resistance to shock or vibration.

Miniature duplex-diode, high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor

Medium-mu twin triode suitable for use in a wide variety of general-purpose amplifier and phase-inverter applications. It is also especially useful as a blocking oscillator, multivibrator, or vertical deflection amplifier in television receivers.

This is a set of measured vacuum tubes for use in TV-7 vacuum tube tester calibration. The values for each vacuum tube will be measured and included for the purpose of calibrating your own TV-7 tester at home. Steps for this calibration can be found online. Three tubes will be included:

• 6L6
• 6AU6
• 12AT7

These tubes are tested at the following settings: Tube Filament Settings Bias Shunt Range 6L6 6.3 HS5-3481 23 0 D Tube Filament Settings Bias Shunt Range 6AU6 6.3 ET1-5672 16 0 B Tube Filament Settings Bias Shunt Range 12AT7 12.6 EV7-6080 10 0 C Note that brands are not guaranteed to match photograph.

Electron-ray tuning indicator with triode unit and two indicating sectors of different sensitivity.

Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.

The Psvane 6550A is a beam pentode with an octal base rated for up to 42W of plate dissipation. The Psvane 6550A is designed specifically for audio spectrum power-amplification and can deliver plenty of power in a push pull configuration with smooth and balanced response. 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.

Miniature, medium-mu twin triode for use as a frequency divider in computer applications.

Beam pentode featuring Novar construction with a special plate fin. The fin provides improved heat distribution and a greater plate dissipation capability. This in turn increases reliability under rated conditions.

Triode using the miniature construction. Its low capacitance and high ratio of plate current to transconductance allow use as a high frequency oscillator and mixer at frequencies below ~300 mc or as grounded grid radio frequency amplifier.

General purpose triode designed for service as an oscillator, detector, or amplifier

Miniature, high-mu, twin triode primarily designed for use in low-level stages of high-gain audio frequency amplifiers.
