I recently picked up one of these radios at a garage sale ($2) and would like to get it working. I picked up a Sam's photofact for it but would very much like to get a copy of the manual. Does anyone have one they could make a copy of for me? I have searched the internet high and low to no avail. It came with original mike, AC and DC power cord, mobile mount but no manual.

Does it run or are you having problems with it? They're a good radio, plenty of nice modulation. I believe that they're double sideband but AM only.

I went to CB Tricks and all they're showing is a picture of the Range Gain II. I'm sure that someone on this board will be able to point you in the right direction.

i recently just sold a couple of the rainge gains, blue cases with a couple of red smaller knobs on the front.
they throw a lower carrier double sideband and a louder modulation, typically only a couple of watts carrier, they are made that way, on the sides are load and tune controls , modulation, antenna load, there are holes in the cover to put a small screwdriver in to tune,
they are definately a different kind of radio concentrating modulation on the sidebands, but not a sideband radio. i believe this was a concept tried by a few radio companies in the sixties to achieve loud modulation.
i will look to see if i can find a manual, you should have one for this radio to operate, like i said they are different.

Have not tried the radio yet. First thing I need to do is clean it up. All dusty from sitting all those years. Then I will test the tubes. Would it be better first time to to use the DC power cord?

It may or may not be easier on the radio to start it up with the DC cord, you sure don't want to just ram 120 VAC to it right off the bat, you need to bring it up slowly with a variac. Both of these measures are redundant anyway. The electrolytic capacitors are old and if they haven't failed already they will sooner or later. Watch out for exploding capacitors and smoke, and keep your face away from the radio, it may run, and if caps fail immediately, at least you know what you have to start replacing.

i would definatley power it up slowly with a variac, i have slowly over a couple of days powered up old tube radios after i have cleaned them up, including tube pins and sockets, all the pots, volume squelch, e.t.c, blow everything out lightly with compressed air then hook up to a variac and 10 volts at a time every few hours for however long it takes, see if its operational, then see if you like it, and if you do start replacing capicators, and any resistors that are out of tolerance, a lot of times the crystals in these old radios have drifted from age , use, e.t.c
sometimes its a lot of work bringing back to life these old tube rigs,
make sure you like it before you start,,,,,,,, jim

Powering the old radio up with a variac very slowly is the way to go.
