Z2b tube rectifier

[bee696]

Anybody used this rectifier before.

In the datasheet, it just mentioned it support 100mA max & 400V. Actually, I want to use it in my power amplififer, it draws 70mA at 260V. How can I estimate the required input AC voltage?

Thanks! Bee

theoretically 260/sqrt(2) = 185 Vac
I go to see the datasheet of Z2b 🙂

Yes, I check the data, but can't find the curve...... : (
