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.
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:
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.

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.

The Psvane EL84 is a high quality output pentode. It has a noval base and maximum plate power of 12W. The Psvane EL84 captures the classic sound of this tube and is an excellent choice for both guitar and stereo amplifiers. 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.
