How to safely get PCB out of old amp/preamp/receiver chassis
I am new to the restoration/repair of equipment and one thing I keep running into is - do I de-solder all the wires connecting the PCB to the power supply/chassis/other boads etc so I can work on it or leave 'em soldered and work on the board in place?
I have found that the way I like to work is to do a little, test, do a little more, test, etc. - but when I remove a PCB it exposes problems with that methodology. Un-solder too many times and the trace/board starts to de-laminate. Work on the board in place and I have touched wires or things I don't want to touch with the iron by accident. Looking for a better method if there is one.
Recently I've run into a power connection on the NAD 1700 that uses the wires tightly turned on posts in the PCB. I am tempted to just un-solder to remove the board, but perhaps there is some kind of replacement I can use so I don't have to un-solder anything (like replacing the posts with a plug of some kind).
