Good question! Does anyone know of ANYTHING else that used an AX9909?
I wonder if Amperex built them for some military project that fell through
and the whole lot got sold to WRL for a song? Who else would want a tube
that doesn't fit anything?

Hello Kim,
Congrats on having your dad's original Globe Champion. I've had Globe
Champions for years (picture on QRZ) and tried lots of different tubes in
them, mostly just for fun and experimentation.
The AX9909s are VERY fragile IMHO. A pentode, they remind me of a TV sweep
tube. The o
K5 in my Gates BC-1T was an Amperite 115 VAC glass-envelope,
octal-based time-delay relay with one normally-open contact. It was 30
seconds delay, so that would be a 115NO030. I found that both time
delay relay coils in the rig are actually running on 230 VAC (as are
all the control circui
If the posted relay scheme is correct for your Gates, I believe both relays K5
and K6 are the old Amperite OD (On delay) type time delay relays. Probably
the same type relay with different time delays. K5 is in the low voltage power
supply and K6 in the high voltage circuit. More safety prec
Sounds good

probably other relative info also on the other pages.

Yes, I worked Bill briefly about a half hour after I sent the question about
who was on 7290.
The station I couldn't dig out was not him. He came on a little later, and
called several cq's with a pretty decent signal despite my local noise.

The AX 9909s are hard to find and some people tell me they

Brian,
I noticed in the manual K5 is listed as a 600 volt Time Delay Relay if that
helps. My old eyes aren't that good either and I have yet to find it in the
schematic or pictorials. My copy is not that good and the pictures are hard
to make out.

I'm not too sure how many of these I'll need, but I would like to find at
least a couple more. They are GE part number GL-1L33 and the value is 100pf
at 7500 wvdc. Physically they are approximately 4.5 inches long and 1.5
inches in diameter. Equivalent caps would be fine as long as they meet the

East coasters sometimes use 40m, up around 7.290.
at 9:15 last night, I was watching the San Antonio Spurs beat the
Phoenix Suns to take a 2-1 lead
Still looking for these meters - need not work. Looking particularly for
milliampere meters in the range of 0-10 milliampere, 0-100 milliampere, etc.
