This is with the RX B+ cranked-down to about 90V.
Unlike the "ARC-5," it doesn't sacrifice much volume
at that low level. If you're wondering how I got
the B+ down: The "green tag" dynamotor in the back
was shipped with about 2 MM of padding and, of
course, was dropped. This warped the end support
for the armature, which is unrecoverable without
advanced tools (I do have another green tag dyno).
I removed the dyno brushes and fed a regulated
adjustable B+ (floating ground) supply in through
the brush contacts, which works well. Have parts
coming to build a 12V to 440V DC-DC board inside
the empty Dynamotor shell. I might even get it done
before Judgment Day.
Am still looking for a GF-10 / RU-15 "green tag"
meter, "coffee grinder," TX control box and
"green tag" RX / TX coils.
Trade or purchase.
