I think i burned up the finals in my galaxy 66 where do i find them on the board

reverse polarity diode may be blown .

The radio you listed "Galaxy DX-93T Base CB Radio" utilizes a 2SC2290 final transistor. This is not a T220 2SC1969 and you cannot install an ERF2030. This is a round and white looking transistor. Replace it with only the same transistor.

gal 66 check the 10kHz switch. or you may have a bad cap, or crystal,.. the 33hp2 check the am regulator transistor... is bad or shorted.

Replace the AM final, then make sure your antenna is tuned to lowest SWR to prevent the final from burning out again.

Take the cover off,and look at the inside for any burnt parts. It has a protection diode, a lot of times this will burn protecting other parts from damage,look where the red (hot) wire goes in the radio, there is a diode coming off there, is it burnt, to check the finals you will need a ohm meter,check the circuit board for burnt trace,s....You will need a ohm meter to check the finals, they are mounted on the rail....hope this helps....

it needs an alignment. The VCO is out of whack.

No, the Galaxy DX44V is a single final radio. It is a 1969 transistor (tr43) mounted on the rear chassis in between the RF driver amp transistor (tr44) and the antenna jack.

Galaxy 66

These radios have a complicated synthesizer circut in them to create the operating frequency and are not easily aligned without the aid of very expencive equipment, Which must be kept calibrated! Call 7086 270 3829 they are Galaxy Experts and have that equipment which is kept in certified calibration, Service monitors, Spectrum analizers and all.

You may have cold solder joints ( broken lead connection/s to the pc board) around the PLL chip area. Also you may have a switch that needs cleaned. To clean the switches, purchase some contact cleaner ( I use WD 40, although some techs don't recomend it ) and spray the switches and pots ( volume control, squelch etc )> Aviod getting any oil on the board. . Good Luck
