Re: Fixing the unrepairable IC7000

Every once in a while if you find a part that doesn't match the schematic, such as you found a 47uF where you? expected a 100uF, doesn't always mean?someone installed the wrong part. Sometimes the manufacturer?will make a change and it doesn't make all the schematics already out in circulation. Sometimes it's just a plain error so when you find something like this, look into it further and don't assume. Bob W4JFA

Your story reinforces what is a very typical scenario during repairs of most anything.? Yes, sometimes thing fail in spectacular ways (lightning strike, water damage) that make a repair attempt futile but in most cases the issue is confined to a specific part or functional assembly.? In a past life I was a commercial radio bench tech and fixed thousands of radios, most of that was isolating the fault to a given part, replace it, and off it goes again.? Odds of fixing it are in your favor, *if you try*.? Hams get freaked out over surface mount and yeah, sometimes getting in there to poke at a test point with a scope can be a challenge, but there's nothing magic about it.? Take your time, be methodical and odds are you'll find something obvious.? You'll never find it if you never try.
