CRT:PVM-4300

PVM-4300, also known as the KX-45ED1 in Japan, is presumably the largest CRT tube ever produced. It was sold in 1991 for $40,000 (2,430,000 Yen) with a variant — the KX-45ED1T with a VT-X5R tuner built in — for ~$41,481 (2,520,000 Yen). It is assumed that it has the same internals as the KV-29ED1, aside from the tube. It has been rumored to have been the huge TV featured in the movie "Camp Nowhere", though it may be a rear-projection TV.
