Re: EL34 power amp project
Hi Andy, no problem them winding the transformer for ratio based on 230v, but they should wind it to operate at the desired flux density based on at least 240v. If not you will be running up towards saturation if it is a Stalloy material, not quite so bad if it is Unisil.
Brass studding should be perfectly adequate stress wise and no danger of getting a magnetic grade of alloy.
