    Damaged dc power jack traces

    Like I said, it takes some skill which you acquire through practice. If you think you've got the skills, you epoxy the replacement trace to the board where you want it, and solder the trace end-points in place. (Use an Exacto knife to cut the trace you need) Be very careful if you're sanding on...

    Damaged dc power jack traces

    You've gotta have some skills in replacing the trace on a PCB. If you haven't done it before, I'd do some practicing on a acrap board fist. I didn't watch your video, but the pic looks like it might be what I'd try in your case. Use a thin wire (I usually cut the lead off a resistor) and...

    Radio Shack score

    Thanks for the heads-up on this. While none of the Radio Shacks in the city near me closed, I checked the flea markets over the weekend and found a guy who dumpster dived about a grand worth of components from the one near him, that I traded him $40 for. Apparently some of the employees were...

    Just some memorabilia

    Yours is newer than any of mine. Apparently I'm older than I though I was. Mine are all priced less than $2.00 each, and it's a shame all those Radio Shack part numbers on the cross references don't mean much anymore. Does this mean we've got antiques? Will the Smithsoneon be looking for...

    Ni-cad's

    Just some more of my experience. If you do leave the batteries unattended for any extended length of time, the capacity will appear lessened, but don't be discouraged. If I cycle mine a few times (charge/discharge) I get my usage-time back (my battery-run capacity). Don't think the batteries...

    Ni-cad's

    I don't know what advances may have been made in NiCad technology lately. This is my experience with the ones I use, mostly in low-power communications. It's bad to use them 'occasionally'. The darned things work best (have longer usage-time/capacity) when they see frequent usage. I have a...

    Help me identify this part?

    All my 1970's era components that look like that are inductors. I don't remember the color-band/decimal point/multiplier configuration code. Since you have a lot of them, Google inductor color code, and get the chart to identify their different inductance values.

    My son's first soldering project

    You didn't show him your haul from Radio Shack did you??? The kid will use-up all your electronic parts before you ever have a chance to. Are you training the next Bill Gates of the electrical engineering community there?

    Let us know when you open your new (unaffiliated) Radio Shack parts store with all that stuff.

    The Standard of Engineering Graduates

    You's gots your engineers, and you's gots your engineering managers. Maybe the managers are directing the engineers these days. It sure seems that way sometimes where I work. The idea seems to be to market the product and move on to the next big money-maker, ... whether or not the last product...

    SCR Rectifier Need cross Reference help

    It may be that your controller is not operating correctly, but the motor itself has a problem.

    Vintage TC-366 Reel Recorder

    Sounds like it has more problems than I originally tought you had. Maybe more problems than you want to deal with. What was the description of the recorder's condition when you bought it? Might it be covered under the ebay warranty of usefulness? If the description said it worked and it doesn't...

    Radio Shack score

    Heck, anything you don't use at those prices,you could easily re-sell at Ham Radio 'Hamfests' in your area. Maybe not at the Radio Shack full price, but at better than whay you're paying. I highly recommend Googleing 'Hamfest' in your city, and finding ones close by to buy or sell electronic...

    Karaoke amp. Only right channel working

    YES! I forgot to mention that a lot of these amps have fuses in the speaker output circuit. Look for fuses on the board that lead to the speaker outputs.

    Vintage TC-366 Reel Recorder

    What you've got is an electrolytic capacitor in an aluminum can. I'm still a little confused about your description of wiring to the motor. I'm thinking that third wire (that I can't see terminated), is probably a ground wire between the motor chassis and the circuit chassis. The two wires...

    Radio Shack score

    You got pretty lucky there. I saw your post and checked the Radio Shack in my neighborhood. It's not one of the ones closing-up shop, so no discounts on their current stock. In the old days, I used to hit the local radio shacks (when they catered to hobbyists), and they all used to have...

    Might be digging himself out from snow and ice if he's where all these big snow-storms are.

    Vintage TC-366 Reel Recorder

    We might need a picture for this. Some older caps had two capacitors in one package. Some had the capacitor, and a separate electrical ground. Is there a manuacturer name and part number on it? The cap itself is 1.5 microfarad at 250 working volts DC, with a 5% tolerance. But the three wires...

    Karaoke amp. Only right channel working

    You've probaby got a circuit problem you're going to need a schematic for. The first thing I'd do, is check your switches and potentiometers. If you've got a bad or dirty one, that might be the problem. You wanted quick. That's what I'd do to eliminate the easy potential problems first. Then...

    Car battery voltage drop

    I think what you're looking for is a 'voltage regulator' circuit. Your car voltage regulator circuit does fine for the car's electrical system requirements. You appear to need a separate voltage regulator circuit with tighter tolerances for your tuning tests. My only question would be, when the...
