[WRL] King DB 68 VFO

[John King]

I have a VFO that covers 80 through 6 meters with KING DB 68 on the front panel. On the rear is a label that say "Distributed exclusively in the United States by World Radio Laboratories Council Bluffs, Iowa". I suspect that that this is  a made in japan VFO. It appears well built. I acquired it today and have not applied power or checked it out.

Does anyone know anything about the KING DB 68 VFO?? If you do, I would appreciate hearing from you. Thanks and 73, John, K5PGW
