Dammitt, I wish I could find my "CRT" book...It told all about the 30BP4...From what I remember, they started having problems w/them right off the bat, due to lack of aluminisation, inadequate getters, etc. There were 2 builds of 'em, not very many on either one, & after the 2nd run ran out, DuMont offered to retrofit the puny little 27" tubes, complete w/a new mask, etc. Apparently, these were Muy Expensivo sets, & the owners raised Heck about 'em, so DuMont felt obligated to try & fix the problem. The book showed a picture of a workman setting the "cone" in a jig, prior to attaching the faceplate/screen. Looked like it must have been a fairly difficult/unwieldy process, the guy had to wrestle the fragile tube by himself, the whole business looked like it would have been like trying to manhandle a large, oddly-shaped washtub. I wonder what the scrappage rate was on these beasts...
