[R-390] Tube extender revisited

[Perry Sandeen]

Gentlemen,

the tube near the base. Solder up short insulated leads to the socket. The hard part is cutting
the glass.

I agree that this can be done and it has been proposed before.  But why do it?

Cutting glass with a dremel tool safely is tricky and very slow.  This I’ve done.

The tube pin material is specially designed to match the glass coefficient of expansion and the
internal elements are spot welded  to them.  Not having done it I don’t know how easy it is to
solder wires to the pins.  Then you still need another tube socket.

With the army manual adapter all you need are two matching tube sockets and some #18 wire.  All
you do is wire the top socket, then thread the wires through the reversed bottom socket, solder to
the tabs and trim the extending wires to size.  

IMHO, the army method is far faster and safer. I suspect that one could make 10 of the army design
before one could make one the other way.  But this is America and one can pay ones money and can
do what’s a personal preference.

Regards,

Perrier
