Same method as above just the newer boards you can find on Ebay.
Just search for "Electronic transformer" and find one that looks like the attached picture. You can find them up to about 130watt and 120 or 240 input.
I found that you can remove about 8-9 turns of output transformer to adjust voltage before it gives up.
Also found that 60vac in almost gives you the same result so if you purchase one with 240vac input it should be able to do lower voltage DHT tubes like the 300b, 801, etc. May not work on 2.5v unless you use a dropping resistor.
