We were able to view color TV on a regular basis after August, 1966. I remember the Perry Como color shows were decidedly inferior to Andy Williams and Dean Martin/Goldiggers shows. I read that TK 41’s were used on the Como show. This Dean Martin Christmas special first aired December 19, 1968. The Martin shows aired from 1964 to 1975. I know that TK 41’s were used on the early Martin shows and in 1968, RCA introduced the TK 44A. The TK 44A was used to tape the Jerry Lewis show in Burbank and just across the hall the Martin show was also being taped.
