[AMRadio] Why I Chose A Globe King 500B

[Brett Gazdzinski]

I have parts from one, and have the schematic.
Its a REAL boat anchor, with very robust components like
vacuum variable caps in the rf section, oil filled solder sealed
large iron I think, pto tuned, and it has every protection circuit
you could think of built in.

Its big, its tough, its ugly, and it sounds military.

Its a very good base to start from, although it has
very noisy blowers that have to be delt with.

Fair radio used to sell them, I almost bought one once,
but the freight charges were very high.

I suppose the truck would drop off a very large crate
in your driveway, and you would have to deal with it.

I think the stock modulator needs help, I never had
luck with 4-125/250/400 tubes as modulators, but have
heard guys who sounded very good using those tubes.
I know the screen voltage regulation is important, as is
the impedance the tubes look into and bias stability.

You could plug in some 4-250 or 4-400 tubes and
make a few minor adjustments, and have a nice amount
of headroom!

I think you can push the transmitter quite a bit, since
its so robust, and run the maximum legal power output.
Maybe even more....
