Default Re: Practical Electronics. Battery Valve Radio Power Supply.

There's a really nice article for a 90V battery replacement from Ronald Dekker here: https://www.dos4ever.com/battery/battery.html with full explanation of the circuit and at the end he shows a quite simple but very nice design.

I haven't compared Ronald's design to the article but I have experimented with Ronald's design and found it very useful.
