AUDIO VALVES: 12SN7GT CV925 B36 TWIN TRIODE
The B36 is an audio double triode with a 12.6 Volt heater. It is a British copy of the American 12SN7 designed and manufactured by Marconi-Osram Valves.
Often used in variants of the famed Williamson amplifier this valve type is finding more use in audio applications as an alternative and slightly more economical high grade 6SN7GT allbeit with a different heater voltage - as you can see from my GEC data sheet shown as part of this product line description.
