Designed for 10, but why not elsewhere?

  Hey Matt,



        No "Technical" reason, guess the guy just
needed 10. Although not as severe as WWII, there were
shortages with electronic parts and tubes during
the Korean Conflict. The 829 may have been the only
jug available, 4D32's were scarce for sure.

       IIRC some Johnson V 2's shipped with 829's.
I'm not sure if it had a big impact on the Collins
32V stuff, but I'm sure someone had headaches from it.

The author of the transmitter article, Stan Johnson, was a prolific author of beginner construction articles for Popular Mechanics before the war. It's not surprising that he would have exploited the 829, which was quite inexpensive on the post war surplus market, and especially in 1951, when 10M was hot. The very first radio equipment I built was described by Stan. It was a regen using the cardboard insulator tube from a D-cell for the coil form. Great guy!
