ablaze 0 Report post Posted September 3, 2003 so for those using DIY amps like the meta42 or PPA, if this works well, we'd finally have our own locally-available, 24V linear-regulated DC power supply. Share this post Link to post Share on other sites
N@Z 0 Report post Posted September 3, 2003 Should at least work great on my META42 headphone amp. Possibly for the upcoming PPA? Thanks for the info & pics Ablaze. Share this post Link to post Share on other sites

dreamie 0 Report post Posted September 3, 2003 ok, lets just assume its regulated. my question is, can you tell if its switching or non-switching? from what it looks.. a transformer and a 7824 regulator? Since a 7824 can limit current up to 1A. If so then non-switching. Share this post Link to post Share on other sites
Firefox 0 Report post Posted September 3, 2003 from what it looks.. a transformer and a 7824 regulator? Since a 7824 can limit current up to 1A. If so then non-switching. It's a linear regulated PSU, although not very well regulated. But it'd do sufficiently. More capacitance & filter is preferable for removing every last trace of a possible hum though. hehehe... The LM7824 isn't the only 24v regulator. Linear Technologies has 24v regulators too. Share this post Link to post Share on other sites
ablaze 0 Report post Posted September 3, 2003 is it comparable to the Elpac 24v linear psu? or worse? how can you tell if its a 7824 anyway? Share this post Link to post Share on other sites
jtfoo 0 Report post Posted September 3, 2003 (edited) is it comparable to the Elpac 24v linear psu? or worse? how can you tell if its a 7824 anyway? It's very spartan, i.e. it is as basic as it can be for a linear regulated supply. Can't go much simpler. I don't know much about Elpac, but if the Elpacs is going to cost alot more, chances are there's lots of filtering done, so my guess is your PSU cannot compete. But as Firefox said, it'll still do the job adquately for your PPA project. Edited September 3, 2003 by jtfoo Share this post Link to post Share on other sites
ablaze 0 Report post Posted September 3, 2003 thanks jt. ben: of course it won't be as good as those dedicated diy power supplies and what-not, but for <$30 and available in the shops, if it works, its great, don't you think? (the Elpac would cost at least twice as much including shipping costs) Share this post Link to post Share on other sites
