W5EHC wrote a early fifties CQ art'l titled "Converting the BC-230." It
has this 3rd paragraph
As it is sold, the BC-230 has several components that will not be used
and should be discarded initially. These are the two VT-25 tubes, the two
VT-52 tubes, their four sockets, the antenna ammeter, and the side-tone
transformer*.... unless fortunate enough to have original power
plug, replace w. octal. Etc.
Elsewhere he sez BC-230s can be had new for $3.50. He advises to, say, use
parallel 6V6s for modulators & 807/6v6 for tx. Etc.
Art'l munges the tank sec'n of plug-in but with unexpected good advice.
230 didn't have swinging link/load-coil per 274N/TCS. Instead
antenna went to tap on shunt-fed tank. & W5EHC within limits retained
this for mobile use. No coax if running in trunk. golf clap.
Art'l an example of how many of these surplus gizmos met death. And
now comes a theory. I maintain many were ordered for a future project
that never was to be. & the ham's decedants conveyed those things to
the present. These are the intact survivors we 'discover' today.
Going back & reading that excerpted paragraph, I'm reminded of the
joke on "how to cook a carp."
Clean carp & season
Nail to oak board
Cook in 500-deg. oven for 2 hrs.
Remove from oven, discard fish, serve board
'rm
*note morse was sent as mcw. Changing load wud have gagged dyno
to a degree on "real A1". Aramture inertia might have helped, tho.
