    Rich KB8TAD comments on his HP: Combination of the old and new FM bands and the old 78 and new 33 RPM (introduced by CBS in 1948) phonograph speeds. Even the phono circuit is unique. The turntable has separate tone arms with Zenith Cobra cartridges for each record type. The red Cobra cartridge has a 3 mil needle for 78's and the green has 1 mil for microgroove 33.
