TUBE DATA LIBRARY


Over the years I acquired quite a few different tubes, but which ones are suitable for audio? And which ones are better left for restoring other vintage equipment. Finally I have an answer! Bellow you will find distortion measurements for all of these tubes as well as triode curves for some obscure triode-connected-pentodes that are not available anywhere else.


Table legend:   
*All Pentodes/Heptodes are triode connected!  (****_T – Triode part of the tube; ****_P – Pentode part of the tube; ****_H – Heptode part of the tube); Part Nr. – tube name; THD% – Total Harmonic Distortion at 10Vrms output into 100kΩ impedance (measurement setup); H2, H3, H4 – levels of distortion harmonics ref. 10Vrms; HX? – are there any higher order harmonics? (>-110dB); Type -tube construction; Vmx, Imax, Pmax – datasheet voltage, current and power dissipation limiting values; μ – tube amplification factor (from curves); Vh – heater voltage; Socket – tube socket type and pin count;
