identifying drake transformers

[fjgaston]

Hi
I've got transformers that I had from a 60Watt Carlsbro (late 60' or early 70')
The code on the OT is 784-213
and 1202 233 on the PT
I can't read the Choke well it seems to be 299 428 but I'm really not sure.

I also have a 1969 carlsbro 60 TC Twin, the seller told me the transformers were drake, but there is nothing written on them.

Can you tell me something about these transformers, are they good transformers or can I find better transformers
