Hi All,
I've always wantd to build a triode connected 813 modulator. Now that I have a good driver design to use the next step was to find a hunk of Iron. I just made a trade for a T21M65 transformer 300 to 500 watts. I wonder if anybody has any data on it? Hipots good. frank

What a pisser, I went to your site first and didn't find the later data. I was looking at the 1935 data.
I could be just brain dead. Very good batch of information HUZ man should go to town and grab a copy to store here.
