Desktop Shortwave Transmitter
The Viking Mobile is crystal controlled, and was sold as a an under-dash mobile transmitter in the 1950s. It uses seven vacuum tubes with an 807 final amplifier, modulated by a pair of push-pull 807s. It uses an external dynamotor power supply, and yes, the rare companion dynamotor is included with this transmitter. It supplies 400V and 800V DC for the transmitter. This unit is either factory wired, or it was done as a kit by an expert.
New price 1952 in the US: $99.50
