Interesting, Fred, I wasn't aware that the 3B24 was a gas-filled
rectifier. However, I used the 80, the 81 (a half-wave rectifier with
greater current capability than the 80), the 83 (a full-wave mercury
vapor rectifier) The 5Y3 was a later version of the 80, with octal
pin basing. I also used a whole bunch of 866's before SSB came along.
They powered a 203-A in one of my early rigs, a 250-TH in a later rig
in 1935, and a pair of HK-54's in another in 1937. (Or were they
HK-354's, I can't remember, yeah, 354's)

Close Walt, only the 3C24 was not a rectifier. Sit back, light up the pipe,
and remember the purple glow of the 3B24. You were right on about the steel
wool. I was wondering how many would remember the dufus that was trying to
tell us that steel wool and a paper towel roll was as good as ferrites.

I also wrote a letter to editor. I was a bit more sarcastic requesting the
B/H curves of steel wool.

Do you still have a copy of that letter? I'd like to see a copy if you
do.
