Cobra 29 NW Classic

My son came home for his home time to tell me that my radio had been getting nothing but complaints, so I opened it up to take a look, he says Dad did you a favor for only 35.00 bucks this guy in OKC peeked it up. Admonished him for his act of kindness and explained that just because I have a FCC/NABER/Extra Class lic ,may not mean I would not know how to tune up the radio. I told him I had already tuned the radio for max clean output. .75 dead with a swing to well Ill leave it at legal. Had a good 100 % modulation. But It certainly did not need the OKC Kid and his golden screwdriver.
So now Im trying to locate these slugs and a variable resistor.

Need slugs for L14, L16. There is a shop in OK City near the truckstops that worked on this radio for my son. They seem to think simply removing these tuning slugs, cutting a jumper and adding a resistor is a tune up.

This shop should be avoided if this is typical of there work. Yes on a peak watt meter it may look good, unfortunately sounded horrible splattering, square wave modulation. Hooked it up to my Motorola r2200 to find spurs all over. Cannot turn down the mod since he removed the slugs, took out vr4 and replaced it with a fixed resistor. Also spread out the coil too far.

Just listed as a word of warning. Be Careful whom you let into your radio.
