Vintage yeasu frequency counter YC-355. Turns on but only 4 of the 5 tubes light up with zero. There is a limit bulb on the left of the face of the unit which lights up when turning on so I know that one also works. Unknown as to whether it works more than this or how accurate it is. It requires a bnc coax cable and believe it plugs into the back of a yaesu 101 or yaesu of the same vintage. Given to me by my radio club during a clear out but they didn't know if it works. Surprised it lit up! I have printed out the instruction manual to go with it. Spares or repairs etc.
Although 4 tubes are working now I can't guarantee they will be working after posting. I will pack this device incredibly well. No returns.
