Oh Yea, Thanks Sheldon,Your design is what inspired me.
Only my diy stepup transformer wouldn't work at that low of frequency and as I couldn't find a suitable small transformer in my junk pile.
Very cool indeed! jer

I went to the Tamura webiste but can't find the transformers.
What can of core are they?
Where can I get the transformers especially Microtan T2?

Or can I make my own with #77 ferrite E-I cores?
How many windings for primary and sec?
