tv tube

[changes]

well here is probably a crazy idea...I've built some pedals but i don't have a clue of anything concerning tubes...i have a tube (PGL-66) that i ripped out of an old tv...can i use it for any sound application?

I don't recognize the part number. Do you have any more identifying marks like number of pins, base size, etc?

Take care,

well might be mistaken cause the letters died away...
it has 9 pins
and as far as i can read says

YUGOSLAVIA PGL-66 (could be PCL-66 not sure)

it also has a symbol like "Ei" probably the brand

did that help???

PCL86 ? eq. of ECL86 (=6GW8) , but the >P< stands for diff. filament,
in this case: 14.5V, 300mA;
the >C< stands for triode, in this case eq. to half a 12AX7;
the >L< stands for (power-)pentode, in this case eq. to EL41, the older (and a little less powerful) brother of the EL84 (9 instead of 12W);
yes, is use-able for audio...

14GW8 is the american name for the PCL86.

>Ei< is the yugoslavian manufacturer (not sure about the name of that country right now, though  :oops: ...

yes
the first number isn't very clear but now you say so i think you're right...
well what about that part???

[puretube]

just imagine you got half a 12AX7 plus an EL84...
in fact the plate-impedance (= outputtransformer)
should be a little higher than the usual EL84 trafos,
but if you stay under 250V B+, it`ll work ok if you keep
the plate current around 35mA.
make a nice clean 5W practicing amp...
(use the right heating!)

Pull the tube out of there, with the related guts?
 I know separating the sound tube's circuit from a TV would be involved, but there it all is...might have to drag the whole TV around, or make a different power supply...involved... :roll:  :lol:
