My client for my electrical business had some boxes on the shelf of his garage. Turns out his father-in-law had run an electronics repair shop. So my interest was raised that perhaps I might barter some of my fee for the equipment, if it's worthwhile.
Leader Audio Generator LAG-125
Leader CRT Tester/Rejuvenator LCT-910A
Leader Waveform Monitor L80-586c ( ? )
Any thoughts?

My client for my electrical business had some boxes on the shelf of his garage. Turns out his father-in-law had run an electronics repair shop. So my interest was raised that perhaps I might barter some of my fee for the equipment, if it's worthwhile. Leader Audio Generator LAG-125 Leader CRT Tester/Rejuvenator LCT-910A Leader Waveform Monitor L80-586c ( ? ) Any thoughts? The audio generator is definitely useful. The other two devices are really only of interest to TV people. The CRT tester is for picture tubes, which nobody really uses or replaces anymore. The waveform monitor is kind of a specialized scope for broadcast TV style waveforms. From my cursory web investigation, this one (by the model number and dearth of info) appears to be an obsolete type that almost certainly won't do anthing but plain vanilla, lo-res NTSC and maybe PAL video. If you're into working on antique video broadcast gear, it's, well it was, essential. Leader is a respected maker of service tech quality test gear, but this stuff is OLD. Which doesn't matter in a basic AF signal generator. |

Thanks John. I figured the CRT tester was useless. The audio generator should be useful for helping build my DIY stuff. My brief online search suggested that the LAG-125 was at least 40 years old.

Do any DAWs besides Reaper come with a tone generator built in? If so, it might not even be useful to have a discrete audio generator. I might have asked you this already keymod, how'd you come about your handle on the forum? You a firearms fan? |

I asked about that years ago. I am a firearms fellow and use keymod freefloats on my evil "assault rifles" here in California, the restricted 2nd amendment state. Turns out keymods are also used for shelves in warehouses as well.
A good sine/square oscillator is very useful in a studio for lining stuff up, etc. If an Audio Precision is a bit much low cost units are available for cheap on line.

A couple of my black rifles have keymod furniture as well. |

I might have asked you this already keymod , how'd you come about your handle on the forum? You a firearms fan? John Kenn gave me the avatar, based on my email address, which is a play on my name - Keith Modugno. I play keyboards, hence I chose keymod years ago and it stuck. LOL, even my relatives call me keymod when I see them. I have nothing against firearms, just don't own any at the moment. I think I would prefer to have a separate audio generator on my bench, rather than worrying about hooking up a DAW while I need to test/tweek my projects. My bench is in the basement, far from my studio rooms. |

A nice little signal generator is a must on any bench!

A "test tone" is not a real signal generator. You can't align a tape machine with a "test tone". Or do a sweep test on a speaker. Or do any troubleshooting/testing that requires a range of frequencies. I can do a "test tone" with my thumb on an unterminated cable. But there is one in my cable tester, too. Not super useful except for audio continuity check on a PA system. And I don't trust any "test equipment" that's built into a DAW, even if my DAW was anywhere close to any of the places I work on gear. |

Got it for $25.00. Hope it works.  |

Studio One has a fully functional generator and scope. Waves makes one too. I mostly use the hardware cause its easy but for calibrating eq's the software is handy too. I still trust the hardware more though.
I also have used zeitgeist and digital scope and both were ok. The plug ins that came with Studio One i found to be nearly as good.

Square waves are very useful for determining low end roll offs and upper band limitations. Good luck finding a good one from software, the Nyquist roll-offs will affect that waveform geometry.

Funny I remember a now defunct amp manufacturer who liked to show off their square wave response till people started to point out that it wasn't therir square wave response, they were clipping the thing! |
