Default modern transformers for an antique push-pull?

Hello everyone. Im about to start my first push-pull style amplifier project. Yes im going very oldschool and using a pair of uv199's.The design looks exceedingly simple, but it gives no specs on the transformers needed, what they should be.

I want to find some modern transformers to use in this, so hopefully the only oldschool bits im using are the tubes and sockets. Any idea where i should look?

Look at other designs that use the same tubes.
Look at the data sheets that spec typical operation, they will show the impedance(s) that the transformer should be... then select an appropriate transformer from the supplier/manufacturer of your choice.

Same as any other PP tube amp.

Hammond Mfg. - Transformer Index

see what you need, then find out what supplier has some.

Or try Parts Express or Madisound

Thanks guys. Im new to tubes and well.. most anything electrical. But ive been having one heck of a lot of fun building simple tube amps and radios.

We all got to start learning somewhere.
