| The complete WS-52 set less accessories. (L-R) Receiver, common power supply and transmitter. The dark, mail-box shape atop the WS-52 was a post war modification which contained a new dynamotor because the original 1200v dynamotors were not reliable due inadequate HV insulation. It was cheaper to install a piggy back unit rather to retrofit a new one. At the top right is an antenna tuner. (Photo courtesy Wireless for the Warrior ) |
