[Elecraft] Light Bulb Dummy Load?

[Helmut Usbeck]

I built a light bulb dummy load which I still have but can't seem to find
bulbs anymore.  The bulb used is a 32 volt 25 watter used in rural areas
where the locals shared generators for local power years ago.  It supplies
32 volts DC and way back when, a collection of appliances and radios were
designed for this.  I understand in some areas in PA it's still around.

Anyhow, I removed the base of the bulb to reduce stray capacitance and
inductance and mounted it inside a large mini-box to an So-259.  A 100 pfd
variable was wired in series with #14 AWG to the outside shell of the
jack(ground). It tuned out any reactance and was adjusted for minimum SWR.
Worked for up to 200 watts. Worked well not to much radation.
