From a collection of gear/parts from a long-time Ham Radio enthusiasts… Here’s a super clean Johnson Viking model 122 External VFO. The unit was part of an estate from a elderly engineer who was a big amateur ham radio enthusiast. This unit is being offered has shown…. Given the condition of all the other examples of gear from him… Pretty sure it would work…. But of course you’ll have to provide or construct a power supply.

Johnson Valiant 2 restored and turbo modified by Dee Almquist W4PNT and case restored by Howard Mills W3HM. Dee did his “turbo” mods on the transmitter which include using a pair of KT88 tubes for the modulators and had Howard Mills repaint the case. This is one of the last restorations Dee did before his death. Includes a printed copy of the manual and mods done by Dee and a thumb drive with the manual. As you can see in the pics is has a ding in the paint on the upper right corner but otherwise in excellent condition. Thank you for your interest and have a great day!!
