I have a 350z from my old man. It has not been powered on since the early 1990s... I know better than to just plug it in and go. At this rate, the capacitors and such need replacing. But from what I understood, the 350z isnt an amp to run. I was hoping I could get mine gone through and be...

I didn't mean to make it sound he has a 203. I just was saying from the smaller amps I got here. But you are right, Let that quad 6 sing.

Here is the link with pictures on how one would go about disabling the pre-driver. KL 503 Pre Driver disable. After some reading, turns out the HD version still has that pre-driver but with some changes to it. (They shoulda just dropped that pre-driver all together.)

I myself can only repair the little 203P amps. Managed to get a few back from the dead. I believe the KL-503 HD is just the KL-503 but without the 1 transistor to drive the rest of the amp. Just curious how many watts were you giving the amp? I honestly never go over 10 watts on SSB to the...

That video had the correct information. This is how it should be: Put the purple wire back to where it is in the picture (Its original spot), then remove the one side on R303. This corrects it so both TX/RX is the same. Upon doing this, I learned my radio is in dire need of help. AM works...

Welp... Just ran into this video... Will report back if by removing one of the legs of resistor 303 will get things going the way they should.

Hello, I finally brought out the good ol Slant Face Roadtalker SSB radio. I honestly forgot when i did the clarifier mod to it. (Must have been a few years ago.). I did open it back up and seen that I already moved the wires and soldered them to the places they needed to go. ***Purple wire...

I used the MX-4 cpu paste. Has been fine so far. I recently took apart the RM Italy 203P and the paste was still fine and not breaking down/flaking away. I suppose I can keep an eye out more on the radios/amps of mine I used it on so far. CPUs and GPUs of today get extremely hot and running...

I lagged, but this is the link to it. 980 SSB Clarifier mod.

There has been about 4 radios that gave me so much hours of grief, I purposely left them up top high on a shelf in the Garage.. :D This way I can't get to them anytime soon. :)

Best you can do is just be careful not to move the wires so much. solid copper can only bend so many times before it just breaks. And when it does break, its going to be hard to find which wire.. But don't stress it too much. May as well make it a project to recap the radio and if you dont want...

From what I understand.... Capacitors leak and eat up traces. Unless I really valued the Super Base, I wouldn't want to recap the whole radio, replace or repair the VCO, and then hope none of the wires while working on it breaks on you. (They are a solid copper wire vs stranded.)

I got it posted. Just nice having pictures to go by. I will use the radio tomorrow as long as conditions are ok to see how it does on the air.

I hear that. One radio that will always be close to me is the slant face Sears Roadtalker radios. I need to bring one back out soon and use it once again. Bummer your Uniden Washington radios gave you grief. They are actually good. (Though, there were 2 variations of them, the 858 PLL or the...

I thought I had done the clarifier unlock the other year on the Uniden 980 SSB, but I must be thinking of some other radio I had. I did follow the youtube video on how to go about it, but I skipped the step on the diode to try and give the radio more slide. I left that part alone. This the...
