Heck your hot mail dont work my links dont work. so try nj7p's tube
data web page I'm sure it has a link to an RCA tube manual. In the back
of the RCA tube manual is many a circuit an the older the manaul the
better the tube circuits are or were. I recall a converter or two back
in the day, all tube radio, on a points/distributor ignition system
car, yeah vibrators those were the days. You know the trick to clean
the contacts on a vibrator 100 watt light bulb in series with the coil
and plug it into the mains

Sounds good, I'll have to check it out.


Then just about the time tung sol invented the 12VDC plate voltage
tube, transistors took over.
I even know how to make a tube out of a dual filament car taillight.
Now there's a real tube.

I wouldn't mind knowing how to do that myself. One of the really good
radio books from Lindsay tells how to make your own vacuum tubes and
transistors. I'm thinking of picking that up as well.

Hey I like to know what country has a code requirement to get your
ticket.

I've been told that "real" hams know code. For now, I'm mainly
interested in listening to news from outside the US and possibly any
Civil Defense frequencies. Would definitely be interested in listening
into any frequency that plays old time radio programs.
