Is there anyone on this list using Common Cathode
triode amplifiers? Some day after I get current projects
completed I want to build a 450TL Push Pull amp. I know
there were Short wave broadcast versions of push pull triode
amps that were ban switched but there was always a concern
about inbalance affecting neutralization. Also, band switching
would make for an interesting impedance matching problem.
Those big Crosleys at VOA had a neat output tuning
system but I don't have the room. HI HI HI. By the way does
anyone have pictures of the old Crosley transmitters?
I saw them in the 60's and they were quite impressive.
What got me thinking of push pull 450TL's was that VOA had
a standby TX that they never used with a pair of 450TH's
and I thought it was really neat. I happen to have the TL's.
While I am at it, I would like to know if anyone has
a 1500T or 2000T for trade of sell. I'd like to complete
my collection of EIMAC triode. I have collected almost
everything from the 15E thru 1000T. Now I need the last
two of the big glass ones.
