Last night I had a dream...
I snuck out to investigate a large and strange building on the outskirts of the city, this building covered four city blocks! When I peeked in one window, I seen two vaccume tubes, each was the size of house! The window was cracked, though the crack I overheard two engineers talking, one must have been new, as the other was explaining to him that the equip was a 100 megawatt xmitter! It was a 60 cycle transmitter. He pointed to the rear of the tubes, at a LARGE balun which fed lines leaving the building. He explained that the balun was properly loaded when a certain voltage was on the plates, and there was a large, variable dummy load which controlled the voltage on the plates, and that the input power could also be varied, as this xmitter was used as a "constant voltage souce." The lines which left the building went to supply homes with the transmitter power. At each home the power was consumed by many individual "baluns", which matched the impedance of the line to a device on the secondary of the balun. Also, many dummy loads (light bulb, resistance heating devices, etc.) existed in these homes. And, there were even devices who's impedance matched that of the lines directly, but contained additional resistance to limit the current they consumed... Then I woke up!!! grin Regards, John |

.. Usually, I reread posts, the above-I did not, I am sure you noticed.
Such as where the constant voltage on the plates should have said, "Constant voltage on the secondary of the balun" etc. But, overlook the errors; you'll get the jest of it. Regards, John |

Errr, notice in the above thread, to my favor, I DID say "jest" and NOT
