morzh is right if you didn't replace the e-caps then one or more of them could be shorted and that will put a serious load on the 80 tube and the power trans.

Looks like there are 3 e-caps on the set a dual #77 on the schematic which is an 8uf and a 10uf, and a single #78 which is an 8uf. All of these can be replaced with 10uf modern caps @ 450v.

Replace those caps before trying to power the set again, also if I were you I would ohm out the power trans to make sure it wasn't damaged at some point.

Schematic here:

If you need a clearer copy PM me.
