General Electric M113YRD

I remember those sets very well. i "cut my teeth" in learning how to do TV repairs when i was growing up, on those cheaply made G.E's. i was also servicing them on a regular basis when i was working in TV shops, even well into the 80's

i believe that the model you have has a "split" chassis (two printed circuit boards that are mounted vertically).
these were notorious for bad / broken solder joints (especially under the tube sockets), drifted resistors, & those "ceramic" (paper in a ceramic tube) capacitors. the design was a poor because of heat build up which "cooked" a lot of the components on the circuit boards.
last, but not least, the compactron tube that does the sync separation & AGC functions are usually the first tube to go bad in the set
