I was wondering if I can use a EI-frame transformer for the zen amp rather than a toroid transformer. I want to make this as cheap as possible without compromising too much. Thanks.
Yes, you can use an EI frame transformer. There are advantages to toroids that I'm sure are posted in a thread here somewhere, so they may be worth the price difference. If you already have a suitable transformer, I wouldn't be paying a good chunk of money just to get a toroid.
An EI frame transformer might be better for your zen than a toroid.
An EI frame transformer will not pass as much power line hash as a thoroid will. But thoroids are good for not radiating "hum" as well as providing superior voltage regulation. In a class a/b amp, voltage demands from the power supply will go up and down. The Thoroid will be better at providing a constant voltage to that demand. The Zen will have a more constant demand on the powe power supply so the EI frame transformer should be just fine.
