ADM-3A Help?

[toml_12953]

My ADM-3A stopped displaying video but I still hear a beep when I turn it on leading me to believe that the main board is working and I have a video problem.
I bought a refurbished Ball replacement CRT and electronics and am trying to install it in the ADM. However, I didn't mark the connectors before removing them.
The video board I removed and the replacement board have seven positions for Molex connectors but there are only have five Molex connectors coming from the ADM to
connect to it: Two from the flyback transformer, two from the coil on the neck of the CRT and one from a transformer on the plate that retains the video board. Would you
be able to tell me what ADM connectors go to what video board positions using the P101 - P107 designations from the maintenance manual?

I wish I could help. The last time I sat in front of an ADM-3A was in high school. That was 47 years ago...
