I personally like the GE 5751 Black Plate triple mica from the late 50's/early 60s. Bought a pair for $75 here on Audiogon from Jim Sautter. Jim is extremely knowledgeable and takes the time to work with you. j.sautter@mchsi.com is his email. He sells under absolutetubes on eBay and jsautter here on Audiogon. I highly recommend him.
Good luck and enjoy the music.
