    Cleaning potentiometers

    And don't forget to mention the actual procedure that you follow. For example is it better to open the pot and clean directly the internals or just throw some spray from any opening and rotate the shaft a few times? such stuff...cheers!

    Cleaning potentiometers

    Hi all! Done a search on the subject in the forum and found almost no info. I thought it would be beneficial for all to gather some opinions and tips on what is the ideal way to clean an old potentiometer. Mostly refering to the ones using carbon but any info on other types is mostly welcome...

    High grade pots?

    Hi! Do you know of any high grade pots and some store to order them from (in Europe preferably)? I know of ALPS but I can't find any resources to buy. Don't know if that is of any importance but I need stereo pots (both linear and logarithmic) with metal shaft and without button capabilities...

    How to make an audio console's power supply better?

    Thank you Ante, this is really nice info. I don't think I will go that deep and make new PCBs. The suggested maintenance and modifications should make things just fine. Can you provide a source (internet link,book) of documentation on the modification you suggest? And any source that I can...

    How to make an audio console's power supply better?

    Ante could you explain the benefit from the modification you suggest (caps across rectifier diodes)? I am of course aware that audio signal quality is greatly depending on the state of the console's internal circuits and that means hundreds of components like you said. But let's forget that and...

    How to make an audio console's power supply better?

    Helloooo! Forgot to ask about this: Is that some kind of extra filter that you suggest? By across you mean one cap in parallel with each diode? What kind of cap? The only hotspot is this. The PSU that has twice the +-17V rails was stupidly set to 220V input voltage. That made it work very hot...

    How to make an audio console's power supply better?

    Ante, why do you consider the other end of the wires as the "load end" when there is a whole mixing desk with plenty of circuitry just beyond? This is the load I was refering to and you are right we must include the wires coming from the PSUs too.I've always been measuring right at the regs...

    schematics for my Soundcraft's PSUs

    sorry for the delay, I've been searching for a scanner... So it's 3 pics in a zip. I'm sorry for the bad quality but they were send by fax to me by the service department... psu1_a = the +17V and -17V rail in the first psu ...note that the regulator for the +17V supply reads something like...

    How to make an audio console's power supply better?

    Hello everybody! This is my first post. I've been around electronics-lab for the last 2 years, occasionally reading some interesting threads but now it's time I join in. I am not an electronics guru so I am more of asking for help than giving but I will try my best. My point is on audio...
