Supply Unit Rectifier No 7 Mk2
I bought this British Army unit at the last Radiophile auction. The army catalogue number is YB07598 indicating telegraphy/telephony use. Inputs are for 100 to 240 volts mains or 12 volts DC using a vibrator, outputs marked +/- 70-100 volts 30 mA DC, 11.5-14 volts 0.2/0.4 amp DC and 33/45 volts 40mA AC. Does anyone know what equipment this was designed to power?
Thanks Mike. |
