KL 203 Fan

[Riverman]

My 203 occasionally gets pretty hot.
Added some small alligator clips to a fan out of an old computer. Problem solved.

Totally!! I have a fan on mine and it helps big time.

Pull the bottom off and replace those crap power leads with some real wire. THEN, bypass the junk they use for a fuse holder with some 12ga wire. Power goes up, temps come down.

If I remember correctly, you must remove the back of the unit and slide the paper from the bottom. The rear must be removed ( slightly repositioned) carefully because of the SO-239 connections.

mine wont let the so239s move any at all

The bottom will slide out but it’s a tight fit. It will need some massaging to remove. After that it slides back and forth freely.

I have one in the truck that was given to me not working. Two of the mosfets exploded. Luckily it did not destroy anything inside. I used 13N10’s and it has been cruising along for nearly two years now with no issues.

I did the same thing to one of those amps, i used some big sheet metal screws that were able to thread between the fins of the heatsink and hold the fan there and ran the wires inside to connect to the 12v. One set of power wires and fan is always on. Great little amp for what it is.

Find a piece of spare / old cable that fits between the fins. Chop off pieces about 1/2 inch long and push between fins vertically to screw the screws for the fan into. I use 24v fans so they whisper on 12v. So quiet you can hardly hear it.
