Cool New Find! motorola VT71m-a

I got this from a teacher for a graduation gift.

well, i need to restore it.

I powered this beuty up on the variac, and not to my surprise, the tubes lit with no audio or picture. needs new caps, and both seleniums.

Charlie, do you have the sams?

also, this thing has the so called "ballast tube" that needs replacing. a couple of those filiment resistors are burned open, and there are others that are intact. (shorted 'lytics i think).

also, anyone that has restored these in the past, is there any advice i need to watch out for?

i restored 2 other TVs, and one radio, but i always ran into a tricky problem.

also, how am I going to rebuild the ballast tube with modernized resistors.

Any ideas? sams would be usefull here.

lol.
