Power supply seems to be 12 volts. I have ICFCD855V's and the power cords on both broke just past the strain relief on the power supply. That shorted the supply and blew the fuse (1.6 amp). I soldered in a new fuse and the supply (with no load) puts out 12VDC. Since it happened to 2 in my house I can't believe Sony doesn't have a recall on these things
Yup, another SONY POS. Had the same problem the transformer is way too large and heavy so the power cord broke right at the strain relief, got twisted and shorted. Of course SONY used these propritary trangular screws so you can't salvage the power supply. Had a Sony camcorder which went bad you would not believe the nonsense I went through to tey to get it fixed. Forget SONY. Just have to train my family members to avoid their products. If I have the time I would try Kalvinb's method
I read that the 1-468-809-11 POWER UNIT is input ac 110 volt and output 8.5volt dc. I got my ICF CD855V at a yard sale. The power cords were frayed and I shorted the PS out. As per Kalvinb I decided to check on that blown the fuse (1.6 amp). As for those SONY proprietary triangular screws, I just took a drill and drilled the heads off. Then the cover pries off and one can replace the screws or just slide it back on and tape it. The fuse is there to replace, but I just ran a bead of solder across the circuit board until I can get a proper 1.6 A fuse. The Dream Machine works great!!

You would need to have a stable 12 volt DC power supply that plugs into a 120 VAC outlet. You can google these, and they come in quite a few varieties. The most expensive are the variable voltage "lab grade" ones, then the bench grade fixed voltage variety, and then the cheap consumer grade 12 volt 1 or 2 amp device designed for CB's and small 12 volt devices. But this will not work, because you are transmitting and could be putting out 40 or 50 watts with that thing. So you will need a good 10 amp to 20 amp dedicated transceiver power supply, unless you just plan on receiving in which case you only need a couple of amps and the cheapie will do. It's always better to have more amperage in a power supply. You then need to think about issues like back-up power with a gel cell 12 volt battery, which also would allow you to use the cheapie supply, because you would have plenty of current to XMIT from the battery. Schematic shows a very basic 12v - 30 amp supply. Good luck!
Look for any bulging on metal capacitors. As they age they can fail, but won't show it until power is stopped for a time. Then when you try to power up the system the fault shows itself Replace all that look that way
I do believe it is a 9 volt charger. Look under the battery cover and it will say how many volts. It is probably 9 volts. Just have to find a 9 volt charger with the same plug as you have. Or contact Motorola for new one. Possibly E-bay
The battery select determines whether you're using a NiCd or Alkaline battery, I believe the "adjust" is used to put the radio into service mode. If there's not an "auxiliary power input" you can hook up the bench supply to, check the battery output for the voltages and polarities, and hook up your supply accordingly.
