Hello Rich from New Zealand!
I've thoroghly enjoyed your vids & tutorials, keep it up chap.
Hey there's a function generator app for android made by keuwlsoft I've found very useful out & about… does sine square triangle, sweeps, frequency & amplitude modulation, much more. Cheers
Solder braid. Awful stuff.
I've found the customer is rarely right.
What a cheap date ! lol just buy a decent Signal Generator for goodness sake. Can't understand how you manage without one, on that note are the other audio fixes of the last month or so finished ?
you can record the audio sweep to a file and then play it in a media player on loop
what was actually wrong with the pot, I didnt see it been tested. Thanks
5:18 – “Beggin’ the Colonel’s pardon.” But, those were probably quality RCA audio cables before being subjected to the force of the weight of the equipment pressing down that closely to where the wire enters the connector end against your bench. I don’t think that even that small gauge of wire can be subjected to such a small bend radius without compromising its conductors. Just sayin’ . . .
A more accurate channel name SaveOurSoulsSOS-cs6np
Hi Richard, came across really small channel the other day. I believe the lad is homeless in Austria, living under a bridge and repairing whatever comes his way. I'm not sure of his origins, but the videos seem to be a mix of German and English. Only 67 subscribers and I thought you might like a look at it. Channel is SaveOurSoulsSOS. He's quite religious, but his content is mainly cobbled together electronics stuff. Might make an interesting subject for your live stream.
Are your RCA cables part of a trio set( video= Yellow, audio =Red and White)? I ask because I just learned that they may have different impedances (video 75Ω audio 50Ω). Thought it might skew the perceived issue.
I don’t know if that’s a US convention or international.
I forgot to put it in the video description. Here is the free audio sweep generator I used

They seem to have forgotten the repeat button
Look into REW room EQ Wizard for a free sweep generator.
Your videos are always very funny. Thanks for the nice entertainment. I look forward to your next video. Thanks and have a nice day!
Hi Richard, your videos have inspired me to attempt repairs on some of my antiquated gear from my halcyon days. I currently have a Roland U220 sound module (1989) in pieces. I have used the incandescent test globe to show a short circuit. The PSU has 3x regulators; +5v -15v and +15v. The Main board is very much op amps logic gates and an intel processor. Separated from the Main board all voltages read correctly and the test Globe flashes and goes out OK. When I connect these 3 voltages individually to the Main board, my test Globe glows at varying levels of intensity depending on the combination of each. Have you experienced this and do you have any advice here?
Regarding the audio sweep: You can use the program "Audacity" (an open source audio editor) to create a sweep (menu: Generate -> Chirp), save it as a file, and then just use any audio player that can loop its playback (like VLC). No special software necessary. You can even play it from your phone, in case the cable doesn't reach to the PC.
Hi Rick.
Seems to me that the little illuminated buttons under every individual channels are cue buttons. That means, when selected in permanent led they drive their input to the cue out (last out) behind. The user has thus the ability to check that input with phones or a local monitoring system before the input volume and the mix. If you press this button the red light should go off on those two channels. After that any input signal applied should illuminate the led accordingly.
I can download the manual but my first approach is probably good
Let me see what I can do for your sweep generator!
