What you are looking for is a transformer that will match 6K to 1 1/4 ohms. Normally the plate impedance would be higher but these tubes are configured in a triode setup for less distortion vs the more common pentode configuration. Something like a Hammond 125E electrically would come pretty closes but mechanically it kinda big compared to the original.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
