The output transformers look great to me, large and heavy, if you like I can post a picture. This very fact is why I want to build this amp, I want to put the ot's to good use. I think the pt may be 250ma, remember this was a replacement and it is larger than the pt in the first chassis that I bought. Right now I am can't decide between a pair of 6v6's or tuned down 6L6's and like you mentioned the ot's will probably match up better with the 6L6's. Sooo many possibilities.
