R-390A/URR after gear clamp replacement and lubrication.

I bought a R-390A/URR that had some band changing issues. The problem turned out to be mechanical. A gear clamp in the RF modules "gear box" was broken and the gear it was supposed to hold in place, was sliding on it's axle. Locating a new gear clamp in Europe was difficult but in the end, a nice enthusiast sent me one for free. The video is from testing the radio after it was put back together again. Both AM and SSB are tested.
