picking the right power suppy

[Walt Langhans]

Hey guys,

So the power supply blew on my rayfine. My tube is a 90 watt and it wants 28mA - 26mA of current. I found one power supply that says it's 80 - 100 watt but only says it have 25mA, and a second power supply that says it's 100 - 180 watt but has 32mA. I'm assuming I should go with the second power supply and just dial it down till I get it in the 26 - 28mA range correct?

Thanks!

Remember Walt the voltages of the higher tube ratings are also a lot higher.

I'd go with an EFR or RECI genuine supply, they have stabilisers for both current and voltage, they cost more but will save their cost on tube life.
