Most repair shops sell or know where but you can find them new on the internet, try Google or one of the search engines, the radio will if stock have to have the output adjusted to use the amp.

Schematic for pc78xL won,t turn on

there gould be a number of reasons for it not turning on but the one I am thinking of is the reverse polarity diode. If it is burnt your radio will not turn on look in the area of your where your power wires come in .You should see a single black zenner diode.Replace it and it should turn on .

What does linear mean?

The word linear comes from the Latin word linearis, which means created by lines. In mathematics, a linear map or function f(x) is a function which satisfies the following two properties:
  • Additivity (also called the superposition property): f(x + y) = f(x) + f(y). This says that f is a group homomorphism with respect to addition.
  • Homogeneity of degree 1: f(?x) = ?f(x) for all ?.

7250PE preamp works, power amp both channels out. Could this be a fuse? Thanks, Mike

Could be possible considering the power amp would be running on a higher voltage rail than the preamp. It really depends on how the manufacturer designed the power supply. If they just have a step down transformer driving a bridge rectifier and then derive the voltage for the preamp by regulating with some for of linear regulator than the fuse theory is not correct. Best bet would be to pop it open and examine what comes after the transformers secondary. Depending on the power this amp is capable of the power supply could be a switch mode instead of linear. You can tell by the weight of the amp, heavy = linear light = switch mode.

Power light on the amp goes on after 5 sec off ultra linear 1200

If you run the remote from the battery you will need a on/off switch. Sounds like the amp is overheating. Also, I don't understand bridge the remote and power. They should be seperate going into the amp.

It should have a blue wire from the harness on the back of the player for turning on the amp, it may also be labeled "antenna" or "power antenna" or "P con". That is the one to run to the remote turn on of the amp.

Cb radio

Hi, A couple of switches and knobs you can check (if present in your rig): 1. auto noise/noise blanker switch - try off position; 2. dynamic squelch control - lower down setting; 3. RF gain - should be at max (clockwise); and 4. Delta Tune - normally should be centered. Hope this works out for you and give you an idea where to start. Good luck and pls post again how things turn up. Kind regards.
