The replacement part is a great deal different, I bought a different Merit replacement for the Muntz 21" but that looks like the original.

Its ready to try a power up after a second round of dressing up connections, all caps now done.
The replacement electrolytic can cap is 500 volt rated, this set has high B+ compared to others Ive done, a good reason to go beyond a standard 450 volt rating if the originals were 475, almost 20% above applied operating voltage.
Some of my solder work needs cleaned up and some of the loose electrolytic capacitors get RTV'd together.
