Still working on this one, almost done un hacking it, now I have a DK of up to 20 watts, no modulation on AM, maybe 2 watts modulation SSB, Is this most likely that IC4 MB3756 that is listed in the Cobra service bulletin, along with the diode change? This is a 1994 model.
I found an extra channel mod and a clarifier mod which was only partially done. Got the tone switch working again, still working on the display dimmer. The power mod was half done as well, replaced the missing tr24 but none of the resistors were changed to go along with it, everything besides the missing tr24 was still stock. I have changed D1,D2,D21,D22 to the 6263 diodes.
Thanks Lee
