I just finished bringing back an SI board that I took from a trashed cabinet and starting on the monitor. I will be putting this board and monitor in an empty cab I found in decent shape for $75. (Franken-vaders?) I have been working with things out on my bench but not sure this is really feasible with the monitor since it is not integrated into the chassis like the other ones I've worked on. I plan on doing as much as I can before reconnecting everything (ring out bottlecaps/BRs, measure ESR, go over the solder joints, etc.)

After that, any advice on the best way to work on this? Working on it in the cabinet doesn't look like fun. I could build some sort of rig to mount the tube in an orientation that keeps the neck safe but allows me reasonable access to the board, but wasn't sure if there was an easier way to approach this. Is there a safe way to power up the chassis without the tube to go through checking the voltages and circuits behavior relative to the service manual. (I suspect it is something in the vertical section as it was a flat horizontal line before I tore things apart) I could tape up the leads that go to the yoke, but was not sure about the flyback, or anything else that might make me regret not sucking it up and digging around in the cabinet to work on it.

Thanks!
