The Tempo 2000 is a full legal limit 80-10 meter grounded grid linear amplifier. Tempo 2000 features include: * Power reed relays for instantaneous and silent transmit-receive (T-R) and bypass switching. The T-R switching operates from a separate receiver and transmitter even when the 2000 is turned off. * A self-contained solid-state power supply. * Grounded grid input for maximum compatibility with modern transceivers and transmitters. * Full legal limit power input on all modes. * 80-10 meter amateur band coverage. Covers many MARS (Military Amateur Radio Service) frequencies adjacent to the amateur bands. * An internal dummy load simplifies exciter tuneup. * A double interlock system helps reduce shock hazard. * Circuit breakers protect the power supply. * The relative RF output meter reads exciter or amplifier power. * The Tempo 2000 is operational within three seconds from turn on. * Black aluminum chimneys and rear panels help dissipate heat from each tube.
