    Another tip... this is from Mike's radio repair. I use GC Electronics Radio-TV Service Solvent to soften up and remove the "Death" Bond from components, Unsolder parts from board, drop them in a small glass jar, like baby food jar size, soak them for a while then remove and pluck the softened...

    RE-cap the entire radio. Look for cold solder joints also. Remove all the Sony death bond glue and look for eaten away component legs and/or shorted parts from that glue.

    The diode mod to IC103 is very common. I do it on rigs that have the talkback bleed through. The transistor on the main board is factory. Usually held down with Sony Death Bond. Remove that crap and use HY910 Thermal Adhesive/glue everywhere the death bond was.

    Sony Bond alternative???

    I use this thermal silicone type glue. HY910. Dries to silicone sealant type phase. Non corrosive and will transfer heat! https://www.ebay.com/itm/224675668251?mkcid=1&mkrid=711-53200-19255-0&siteid=0&customid=link&campid=5336136228&toolid=20001&mkevt=1 And yes, I will use it on large caps...

    Well..... Cobra 29-150w LTD????

    Yeah, I have a few stand-alone amps. Nothing big... 4 pill and smaller. This would be more of a " will it work" experiment and possibly sell it if it last kinda deal. I got plenty of 29s and I only paid $35 for the board. The 2879 however would be tough to part with. Gonna be on the lookout...

    Well..... Cobra 29-150w LTD????

    Well Tree, I bought it off eBay from a seller that got it for a repair part for a customers radio. I think the Stryker SR-490 and SR-497HPC used these in the early version. Yes, it has been sitting around for a few yrs with no radio to call home. PCBX-0615R5 is what I have. Some info in this...

    WTB.... Cobra 25GTL bezel. Korean or Taiwan era made.

    I have decent looking and working Korea era 25 GTL. Problem is the channel switch support on the bezel is broke and missing several pieces. No super glue fix for this one. Anyways, just a bezel or an entire parts rig for the right price would be great. Hit me up with a PM if ya got something...
