Besy Way To Desolder Amp Board Tabs

Wire Weasel

A friend of mine is going to be bringing me a Palomar Blue 225 like the pic. Has lost about 25 watts of power but still working. Looked inside and says there are two diodes that have popped loose presumably due to heat ( I told the boy to mount a fan on de thing). Says diodes have popped loose from the solder side of the board and the board will have to be unmounted from the overall unit. Says there are large solder tabs in the corners presumably connecting the board ground to the case. I can check/replace/resolder the diodes for him but have no experience desoldering the large corner solder blobs from an amp case.

What's the best-easiest way to do this? I have a large soldering gun and small butane hand torch and pretty good soldering skills.

Thanks for any tips!

Use the biggest baddest soldering iron you can find and use a small pair of needle nose pliers or a knife blade to separate them Clean up any solder blobs after and resolder up good when finished.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
