    Repairing bent or broken external heatsink fins?

    Honestly, I'd leave it alone, probably not going to cause any problems. It just looks ugly. You could straighten it and solder it, but the finish is anodized, so you'd have to send it out. Any paint would probably reduce efficiency. If it bothers you that much, find a replacement.

    I'm addicted to tannerite, every time I shoot rifles I have to shoot one.

    Pioneer sx1250, marantz 4400, marantz 2240, and other goodies.

    I also have a couple marantz tape decks with really cool looking meters. One is the aluminum face we all picture when you say marantz. One is a horizontal one that doesn't fit the typical marantz style at all. What are those worth? They're in good shape, and worked 25 years ago when they...

    Thanks for your estimates, more than I figured.

    This is silly, for no particular reason, I would like to know the value of some of my gear in it's current condition. First up is my pioneer sx1250. The main amp worked beautifully up until a couple days ago. Then the dial lights went out, and it went silent. The preamp was all crackly when...

    Panel light replacement

    I have never eaten a grommet, but I'm pretty sure I wouldn't describe it as gourmet. From my experience, rubber tastes pretty nasty. You can probably find something that will work in here. https://www.amazon.com/Cal-Hawk-AZGA125-Grommet-Assortment-Electrical/dp/B002X4AFL0

    SX-1250 speaker terminals.

    Yeah, well the 1250 doesn't like the 14ga wire I'm using. I did tin the wires.

    SX-1250 speaker terminals.

    Meh, mine ain't worth much, the preamp section is toast, it's missing parts. Somebody hacked the am antenna off. I'm just using the main amp section. The main amp still sounds incredible!

    SX-1250 speaker terminals.

    I've decided the old push button originals suck bad. The springs are weak, and they're difficult to get a good connection with. I was thinking of making a new plate to replace that entire area, cutting it out, and putting binding posts there. I was also thinking about doing away with the C...

    Help needed about a mixer and cables and... :)

    The xlrs are outputs. A headphone to rca connected to line one or 2 on the mixer will do it.

    Elementary question about power switch and fuse

    Well, I would put the fuse first, because I've seen power switches fail catastrophically. I've seen them wired both ways though, and there's not much difference either way.

    Relay Question

    Any of those will work, but they're way overkill. You only need a 10a relay. I doubt that solid state relay will even get warm with a 4.2a motor.

    How often do you clean the soldering iron tip?

    I don't have a number, but I clean it when it looks scuzzy. I also use one of those brass scrubby things with a weller wes 50 station. On my second tip, abused the first one melting plastic and stuff. I also have a tiny chisel tip. That brass wool stuff works so much better than a sponge.
