Please Check my soldering!

Hi, I'm fairly new to soldering and I often see on forums/soldering guides people criticising soldering in pictures saying that it is rubbish/unsafe.

I've just repaired my trusty Quad 34 pre amp and fitted a new power socket and power switch as both were knackered. I've soldered as neatly as I can and the amplifier now works fine. Just wondered if you could have a look and advise if my soldering is ok? Thanks.

Very neat job. Well done

From that shot, it looks OK. A higher-quality close-up may or may not reveal any errors.

Good job leaving the insulation close. You can clean off the flux... or just leave it. Wouldn't be too big a deal to leave it on with most types of rosin-core solder.

Thanks, Have another pic!

Probably ok...

The last pic shows the green wire... may or may not be ok, can't see really.

It is possible to make a reasonably good looking joint like the one you have where the wire is really only held in by the flux/rosin.

To take an extreme closeup, take a magnifying glass, place on the lens of the camera, press just enough to enable to focus feature, and then get as close as you can and still stay in focus, click...

depending on what is on the other side of that lug, you may or may not have enough solder there... another consideration.

Another thing, when making connections of this type it is good idea to mechanically bend the wire around the lug (after going through the hole), this way there is a larger surface area for the solder, and a mechanical connection to the lug - this makes a stronger joint, and has less chance of stress cracking in time...

The military does things this way for that reason.
