/diy/ - Do It Yourself

For prototyping I get isolation transformers, a store here carries some that are 120-230V both sides, with multiple taps and are rated 65VA for about $25. Or Ebay.

230V rectified with 1N4007 will give roughly 175~325V depending on what tap I use which is plenty, Buy 2, wire them in series on the secondary, parallel on the primary and you get up to 650V for bigger stuff but I would use a heavier diode than 1N4007. Also gives you the option to use a tube instead like a 5Y3 or 6CA4. Or be whack and use mercury arc rectfifiers.

Shitty thing is you'll need separate transformers, one isolation, one for a heater supply, etc. for whatever else you'll need but it does allow for greater flexibility.
