Quothe Tony Duell, from writings of Sun, Sep 08, 2002 at 12:25:39AM +0100:
I have come across dual triodes and most likely have a few of them. :-)
Not sure what the number for it is, however.
Not sure what
5.1 audio is, but a single tube could be a dual triode,
and hence be used for stereo (is there such a thing as a quad triode?)
It is a dual triode (I am truely suprised you haven't come across this
valve). The European code is ECC81, indicating it has a 6.3V heater ('E'),
it contains 2 triodes ('C' for each of them) and it fits a B9A (noval, 9
pin miniature) base ('8'). I've never seen a quadruple triode. The most
complex common valves in the
UK were double triodes, double diode triodes, triple diode triodes [1].
Ah, yes; somewhere around here I also have some "duo diode hi mu
triode" valves/tubes... There seemed to be a lot of interesting
valves/tubes used in television sets, with many more elements in them,
than those found in radios and stereo equipment.
