This VCO is a replacement for the green VCO commonly found in the Cybernet range of SSB Radios.
eg: 
Ham International Concorde 2
Ham International Multimode 2
Major M588
Tristar 747 to name a few.
​
This replacement VCO has extra range so should cover most rig conversions.
Each VCO is hand built using quality components and each VCO
is tested before dispatch to ensure a good working unit.
