Ameritron ALS-1300, a 1200 Watt amplifier. Works from 160-15 meters bands (1.8-22 Mhz). It needs 50Vdc for power it which can be supploed by the ALS-1300PS. Uses 8 TMOS-FET 50v transistors, forced cooling (fan), the power supply likes 250vac but can go on 120vac if low power if used on full wave transmisstion (cw/rtty).
