Hammarlund Four 20 Transmitter & Four 11 Modulator both in Excellent Condition

This Hammarlund Four 20 Transmitter & Four 11 Modulator, are both in Excellent Condition. They were made in 1947.

  The Four 20 transmitter is a 20 watt CW transmitter. Whith the modulator you can use the Four 20  on phone.

The Four 20 Transmitter comes with the factory 10, 20, 40 and 80 Meter Hammarlund coil set.

 The Original Manual is also included.

 This set is part of a collection of a client who has been collecting vintage gear for many years and is selling due to having to move.

These two units were often paired with a Hammarlund HQ-129X. Below is a link to an ad from 1947.

  I have not powered up either unit as I think the original paper capacitors should be replaced before it is put into service,  but they  look to be in great shape.

 I am selling them as is, as described.
