Icom IC-R75 Receiver Power Jack Repair

[@n2pqj524]

My good friend Jack, K2JX passes along two very important grounding observations. 1) I should be using an anti static wrist strap when working on high impedance circuits {one volt looks like a million volts to the components.} 2) Touch the soldering iron tip to a ground before soldering on a motherboard. Static or other stray voltages can flame the microprocessor in a Nano second! Will do!!

Very informative! The ragtime music adds character as well 😁

Hi, this was great, followed it to the letter and my R75 is like a new rig. Will you be following this with a video on how to fix the R75 extension speaker jack as anything I plug into the jack crackles? Regards DW

No

That was always the one and only weak link that darned power jack! Had to have mine fixed. I’d epoxy it if I ever replaced it again. Epoxy can be dissolved so it isn’t permanent. GREAT radio esp with mods! Adding to my archive in case it ever needs another fix. TY for sharing! BTW what filters do you have in it as optional?!

[@n2pqj524]

I did have the DSP filter in one of the rigs. The other one was stock.

Ditto. I bought one from ebay and the very arrogant seller was adamant there was nothing wrong with the power socket within a very short few days it had stopped working altogether so had to send it to ICOM but back soon with a rock solid dc power socket…

Hilarious at the end! Get a hammer, Sluggo!
