It uses 2 silicone diodes for the rectifier.
All it needs is a new 6FD7 tube and it should be back up and running again.

I would've bought that set, myself. It was the TOTL for a 19" that year.
If you have a 6DR7, IIRC it is a sub for the 6FD7. At least, you could try it, until you get the FD.

I thought about that but sadly enough I pretty much had every single tube that this TV needed in my tube stash except the 6FD7 or its subs...

Do you have a sub guide?
Many times the subs listed are only close tube designs and will, only once in a while, cause a new problem. IE: the vertical hold will be critical or the lin or height won't adjust properly. The 6FD7 and the 13DF7 is a Philco designed tube.

I do have a tube substitution guide and I saw what subs were listed for this tube and I didn't have those tubes in my collection so I just went ahead and ordered a new one over at AES it was only a $3 so it wasn't a big deal.
