Continuously variable output form 100V to 5KV displayed on 0 to 5kV Digital Voltmeter. E.H.T. circuits are fully floating so that for certain applications the positive and negative terminals may be connected to earth. E.H.T. output are taken from 4 mm sockets and provide 100V to 5KV at 3mA. A center tapped socket is provided to give ± 2.5kV output. Additional pair of 4 mm socket at 19 mm spacing are provided giving 6.3V AC at 2A for filament supplies. An illuminated on / off switch is mounted on the panel. Housed in metal case. Operates on 220 / 240 V AC 50 Hz. Size 26 x 23 x 11 cm
