Lysco 600 is a transmitter that dates back to the early 1950s. At $190, it was an expensive and very well designed and built transmitter back then. It can be operated with a crystal or you can use the internal VFO. It covers from 160 Meters up through 75, 40, 20, 15 and 10 Meters. The tube lineup is a 5U4, VR-150, 6AG7, 6AG7, to an 807 as the amplifier. Runs about 50-65 watts CW (depending on band) and has a built-in power supply. Input can be lowered to QRP level output. Unusual for its day, it has a low pass filter built onto the output inside the cabinet.
This Lysco transmitter was manufactured in Hoboken, N.J. around 1949. It is a crystal controlled unit which uses 3 6AQ5 tubes.
