Small triumphs in vector collecting

There is no questions in this story but I had one of those small spurts
of success today, that we all need when working on bring a game back
from the dead . There are some interesting points I learned along the
way that may be useful to the group
        I purchased 2 dead lunar Landers from an Op well over year ago. As I
loaded them into my trailer his closing words were "maybe you can make
one good one out of the two". Both cases are in B shape. And were
complete with boards and monitors.
        Upon getting them home I proceeded to plug both of them in, checking
for signs of life. One monitor had heater glow and the other had none. I
put both in to test mode but got nothing in the audio department
indicating life, so I packed them away for later, thinking I was in for
at least one monitor and 2 boards.
        About a month ago another collector showed interest in a trade for one
of my LLs for his Star Wars so I figured I was time to get going on the
repairing of these machines. It had been over a year now and I had
collected 2 spares B&W monitors (one GO5 and one WG19200) as well as a
known working board set.
        Opening the first machine up I found a bunch of cut wires I didn’t see
before. Some wires were for the audio and some for monitor connections.
Once I wired it all back together I had heater glow on the totally dead
monitor (Small triumph one)
        I pulled both monitors for cap kits. I Emailed bob Roberts for 2 G05
cap kit and they arrived days later. I wasn’t until I went to put them
in that I realized that many of the parts were wrong. For those who
don’t know (and I was one of those people until now), Electrohome made 2
versions of GO5. The G05 (TM-146) and the G05 (TM-151) The G05
(TM-146) was made in small numbers and it distinctive in the fact that
it has a separate power supply, rather then having the power built into
the deflection board. As it turns out, I have the rarer G05 (TM-146) in
both of may machines. Frustrated that I could not do my cap kits that
night I unpacked the 2 spare working monitors I had picked up over the
past year. I had never opened them so when I did, I discovered a G05
TM-151 model and a WG 19v200. Both units have the same pin out in the
connection plug between them selves, but the Lunar Lander machines I
have are wired for the G05 (TM-146), which it totally different using 2
connectors for the power and x y signals.
        Two make a long story short, I made an adapter cable to mate the older
wiring to the more common monitors and plugged it in today. Holly crap
the thing came up and my board worked! Excited I pulled d the board for
the other machine to try it as well, and that works too! I the realized
that the reason the one machine did not come up in a "blind test" was
that the audio wasn’t working on one machine and the plug it a bit funky
on the other machine so it doesn’t always go into test mode. But 2
working board and I monitor set up that is usable ! Woo hooo!
        Anyway. I’m going back to see if I can get the original monitors up ad
working as one of them has zero screen burn. Alas, I suspect that the
flybacks are dead on both so If anyone has some to offer send me an
Email.
