Vintage collins 51j-4 general coverage tube radio receiver with 3 mech filters. Collins 51j-4 general coverage communications receiver with 3 mechanical filters. Very nice working radio. Chassis is very clean with no rust – face has a couple of small marks on it. All controls are working and i was able to pull in stations on all bands. The only thing i did notice wrong was when tunning the dial towards the left in the last 2 it squeaked a little and had some resistance to it – turns towards the right just fine – so needs some adjustment. 19 rack mount with rack handles. Coverage from 540 – 30500 khz in 30 bands. Selectivity of 6 to 1 khz in plus phasing to give additional control over bandwidth. Avc on/off (automatic volume control). Headphone / speaker jacks and 600 ohm output using terminal strip. If output jack (455 khz). Anl (automatic noise limiter). Calibrator at 100 khz intervals. Wired for 115 volts and can be set for 230 vac.The item “Vintage Collins 51J-4 general coverage tube radio receiver with 3 mech filters” is in sale since Wednesday, January 21, 2015.
