Choosing the right transformer?

Hello,

Allright so the problem is choosing the right transformer as the one mentioned in the project is discontinued.

The one I am talking about is "Hammond 269AX" which can be seen in this datasheet

So what I need is, is help with choosing a random amplifier suitable for tube amplifier and meeting the same specs as Hammon 269AX.

If anyone can help I'd be very grateful.

Oh nice to see its still available, cant order from there though...shipping would be 40 Pounds for me :S considering how much the thing itself costs its too much.

Anyways I am trying to find a similar transformer built by INDEL

Have a transformer custom wound, here for instance...

Netztransformatoren

They are located in Poland , distributor is in germany, and they seem to be good quality.

Thank you for the tip

Ok now I have managed to secure few places I can get my transformers from but the underlying question remains...

How do I know which transformer is really good for audio? I haveb been reading about all sorts of transformers with iron or silver cores etc...
Can someone tell me If there is a good way to determine if the transformer is good for audio purposes?

It is a power transformer, not an audio transformer. So long as it is good enough quality not to be mechanically noisy or electrically faulty, sound quality is largely redundant.
