Yea. I don't have any. I figure it's cheaper just to replace the switch.

Took only a few minutes to take out the chassis and disconnect from the speaker. I took pictures to make sure I wire it back up properly. No soldering needed! (Actually, kind of a bummer). I will, however, since I need to buy a switch, I'll pick up another push button switch to solder in there...

Thanks, guys. First step will be to crack open the amp to see what im working with. Hopefully I’ll have time this weekend.

Should I be worried about high voltages? Like I said I’ve never done amp work before

I've got an old Marshall MG30 that I keep in my home office for noodling around. I had the power switch break off this afternoon (it's a simple rocker switch). How would I go about fixing it? I'm assuming I need to take the amp apart and see if there are other stray parts that broke off. I...

Does the crackle happen as the pot is rotating?

Do you still want to be able load a battery in there after swapping the power jack?

Pics of your build may help. You can always add a jumper cable. Are your ICs properly powered with correct voltages?

Could be a cold/bad solder joint. Can you provide some pics of your build? We might see something you don't.

I’m sure Chuck would know what’s wrong just by looking at the schematic

The resource thread in the test kitchen here has some good stuff

At least you picked up the $9 discount, lol

Report back on the readouts for all 8 legs of the chips starting with the upper left corner and working CCW.

Do you have a multimeter? That will help check voltages on the chips.

Clean the tracks with your iron. There look to be some bridges in there or it could just be the pick. Has the layout been verified?

Poster tack or Velcro. Boards can be easily moved with either

Reflow your solder joints. Some of them look cold or not enough solder. See if you can trim down some of those some more for, you know, neatness. I’ve got this board in my backlog, so I’m hoping you get things working and post a build report.

To learn the basics of opamps try breadboarding a mini muffin fuzz (inverting) and a Dist + (non inverting). There are breadboard tutorials in the Test Kitchen here to guide you in the right direction.

There’s only 1 place for hate around here

Post a link to this build in the PHB thread for this to count as a submission. Otherwise it YABR (yet another build report)
