A perplexing puzzle: National NC-183D power transformer

Stay a bit longer at work one day and order up one of these?

I didn't verify dimensions, but specs look fine.

Plenty of ways to kludge something together, power up those junk transformers and see what you've got?

The transformer shown doesn't have enough 6.3 volt current capacity.

You're right, my bad!

Even the 5 amp spec is a little on the weak side, as the heater currents add up to about 5.25 amps. I suspect that it is the same xfmr used in the 173 and 183 and a couple more tubes were added in the 183D (double conversion) design. No worry there, as xfmr ratings of that era tend to be quite conservative.

That's the odd part, I don't have any!
