I had a neat Airline with a good tube, and, a chassis full of rust. I rebuilt it, then tried it on my variac. At about half way I heard the vertical. Then, a snap, and, B plus crashed, went to negative, and, at 225 - volts, I gave up. I found out flyback was shorted. I had heard an arcing sound when voltage suddenly crashed.... There was a boost cap of10 mf 350 volts. It kept going negative. A lot of checking, and, no good Then, rusty strap on picture tube broke, tube slid out, and, POW. Neck broke off, and, rest of tube broke on the floor. I gave up, stripped it, and, junked the set.
I have the same model as your M-105, now. It intermittently played, then went to a raster
The rubber AGC wire going to flyback was rotted, and, shorted. After a long time, I found a wire. But, wiring on agc circuit is qu9te different....
