50 watt amp project

[TiCatFan]

Greetings!

Sounds like a big project so it's good you are taking your time to check things as you go along. From what I've seen and heard, most problems with electronics that does not work comes down to solder connections.

In a new build like yours, there is the added bonus of solder bridges. Some of those are so small you either have to use an ohmmeter - my personal favourite kind of meter - or just go brute force like a Cockney sailor and score around the pads and traces with a sharp but fine knife. In any case, you need good lighting to see the board properly to then see where bridges are that shouldn't be.

That sounded Shakespearean.

Cheerio

Thanks Sherlok, you make some very good points. The older I get, the more important good lighting becomes. I have a nice magnifying lamp that helps me see all the small stuff on the boards but I have been thinking of improving the overhead lighting also. Perhaps that should be my first job. You make a very good point with the solder bridges. I have tried to see if anything looks wonky but I think it's time to pull each board out of the box and get a good view, top and bottom and like you said, make sure there are no bridges.

thanks...
