Hello everyone.
I did a favor for my neighbor and he in turn gave me this RCI 2990 witch I thought was 2990dx that use to belong to a friend of his. Anyway the radio only does about 40 watts on AM and 100w on SSB. The faceplate had the entire writing wash out. like somebody clean it with some solution that erased all the lettering. So thinking that it was a dx I bought the sticker face plate for it this is when I found out that is not a dx. Also somebody install a heavy duty power supply. Do anybody knows of a good technician near new York city that could retune this radio recalibrate the meter etc. and get it back to factory specs? Also some tech made a nasty looking hole on top of the cabinet to install another heat sink that attaches to a rectifier that goes to the power supply. What’s up with this mod?
I was talking to a guy a few weeks ago that he was using a similar radio and he claimed he was pushing 400 watts “barefoot” He said somebody work on his radio and change the finals, was this guy pulling my chain?

On page 36 of the service manual, the component view of the main PC board, clearly shows the typical lithium coin cell used for memory retention by a number of radio manufacturers. A call to Ranger Support and Service can provide the parts you require.
