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 5Y4G is designed for use as a power rectifier in AC operated receivers.

The TAD ECC81 / 12AT7-Cz is selected with regards to a tight balance of both triodes making it ideal for the use as a balanced phase inverter. In addition to the perfect symmetrical systems, the strong amplification characteristics of the TAD ECC81 / 12AT7-Cz support increased dynamics of the output stage when used as phase driver or phase inverter tube. Q: When does a power tube become a Premium Selected power tube? A: All power tubes labeled Premium Selected have passed the following tests:
- Plate Current (PC) and Amplification (TC)
- Low Noise Test
- Microphonic Test
- Sonic Tests
- Shock Tests
- Listening Tests
- Shorts & Leakage Tests
$24.95
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Shouldered glass (ST-16) envelope.
$27.90
Miniature type pentagrid converter designed for use in low drain battery operated receivers.
$99.90
Miniature high-mu twin triode especially suited for use in resistance-coupled voltage amplifier, phase inverters, multivibrators, and other applications in which high voltage gain is desired.
$49.90
Electro-Harmonix 12DW7 dual triode preamp tube. Made in Russia.
12DW7 combines one triode of 12AX7 and one triode of 12AU7 in a dual triode package. System 1 (pins 6, 7, 8) is the high-mu 12AX7 triode and system 2 (pins 1, 2, 3) is the medium-mu 12AU7 triode.

The all new TAD-EL84-STR Redbase brings together the best of both - the famous EL84-Cz and the EL84M. We opted for the thickest glass possible and the heaviest construction available, just like the Russian EL84M, and combined these features with the sonically most promising cathode plate options, in order to meet and exceed the tonal quality of the EL84-Cz especially with regard to its linearity over the entire frequency range. Finally we added the gold grid wire in order to improve overall reliability. The sound can be described as very harmonic in the middle and treble frequencies, without adding too much power to the bass. The result is the best EL84 in current production. Note: Due to its diameter of 22.5mm, the TAD EL84-STR does not fit into older Marshall DSL401 made till week #20 in 2014 and the UK made VOX AC15 TBX amplifiers from the same time period.
Starting at $24.30
Triple grid general purpose detector amplifier. With the exception of capacitance, its electrical characteristics are identical with those of the 6J7G and 6J7GT.
