    Squawk Box

    Geranium is a genus of 422 species of flowering plants. Germanium is a metalloid chemical element sometimes used to produce electronic components. ;) One of these things is not like the other.

    1/4 inch mono jack 3 pins

    I was just hoping you'd start referring to the parts of the connectors as tip, ring and sleeve to reduce confusion. I linked the Wikipedia article on phone connectors as it includes that information. Try not to get frustrated or irritated too easily as we understand the difficulty with...

    Squawk Box

    Be gentle in your soldering efforts as this type of circuit board material (resin bonded paper) is notorious for pad popping.

    1/4 inch mono jack 3 pins

    It might be helpful to start using some standard terminology in this discussion. https://en.m.wikipedia.org/wiki/Phone_connector_(audio)

    Intermittent audio from speakers

    Check for bad solder joints on the relay or even reflow them regardless of apparent condition.

    Wire spool - what is it worth?

    Beldfoil is a trademark of Belden so you know what brand it is now. There should be a product code stamped or embossed on the cable jacket.

    Banana Test Connector

    If you're looking for a precise subcomponent, it may not be available but here's another source. http://www.keyelco.com/category.cfm/Banana-Plugs-Jacks/Banana-Plugs/p/459/id/461/c_id/807 Are you now looking for an inline jack?

    Banana Test Connector

    Mueller, Pomona and EZHook are the brands that come to mind. What you've pictured is not complete. There would be some kind of plastic handle covering the left end of the post.

    FM fading

    You can buy a premade folded dipole for a few dollars new or find one at a local thrift shop for less since they're packaged with every stereo receiver sold and often donated, sometimes unused. For best reception, the top of the T needs to be perpendicular to the signal source.

    Hey, are you in Brizzie?

    I have pondered the Australian penchant for slang and extreme abbreviation and concluded that it's probably a byproduct of inmate culture where the prisoners are always talking in made up codes to confound the guards. :p

    Mood Light Project

    There's no information here regarding purpose or function. The title is vaguely suggestive of a device that senses something from a human and maps it into an LED-based lighting display.

    Roland E68 keyboard intermittent sound

    This still sounds like a mechanical flakey on the PCB, but somewhere in the output path to the speakers, probably the last amplifier stage since all others are likely to be in common with the symptom-free modes. To address your specific question; if the problem is a component failure...

    Roland E68 keyboard intermittent sound

    The symptoms suggest a fractured solder joint or PCB trace on some common bus feeding all keys. It's more likely to occur in an area where the PCB is poorly supported and thus capable of more flexure than other areas. If this is the problem, it will be difficult to spot visually. Use good...

    Wiring 5v to a 12v powersupply

    Is there any reason why you can't just use one of these car USB chargers or the circuit board within? Get one with two 1A outputs or better if you like.

    Help: LED Visor Light Bar, audible high pitch noise.

    Provisions of the Magnusson-Moss warranty act may apply federally and most states have additional warranty laws that deal with concepts such as suitability for intended purpose, etc. This may be an opportunity for a law enforcement officer to delve into consumer law a bit. :cool:

    Mic preamp repair help!

    The residue on the top of the capacitor, C300 in image 1726, is a potential problem. It's out of focus, but looks more like electrolyte than glue. Does the PCB hang upside down in use? The glue around the bottoms of the various capacitors is no problem. The residue around U410 is solder flux...

    Car speakers work on AM but only right side work on FM

    Of course, but where in the chain does the AM audio signal get distributed? If it's after the, presumably dual, volume-pot-controlled preamp, that would explain the intermittency experienced while adjusting the volume pot in FM.

    Car speakers work on AM but only right side work on FM

    You may just have a bad volume potentiometer (the component behind the knob).

    Help with strobes!

    It would take at least 5 4017s and quite a bit of additional logic, what Hop was referencing I think, when he used the term kludge.
