hi all,
there is any chance to get the schematics of JC-1 power amp?
it is very important in order to repair and restore an old set.
thanks a lot for any help.
best regards,
williams
actually, there really are some JC-1 power amp schematics in that thread. john hinted they might not be exactly what is currently being built and shipped.
there is also some useful commentary on operating points, stability, thermals, all kinds of useful info for study.
I downloaded the 64 bit version of 7-zip as running win7 enterprise. Installed. Opened file. It contains 2 scans of circuit diagrams possibly from a service manual. Nothing exciting though. Not sure why your computer is failing you today. ostensibly what mlloyd reminded me JC had posted with caveats before.
I think I had this "not opening" behaviour some long while ago with 7Zip, I think I uninstalled it because I could not get 7Zip to work in opening Zipped files.
But I thought I still had another unzipper, but I can't find it.
Its an RAR file or I should say, it appears to work without issues using WinRAR. Like all graphics file handling software, you have to download and pay for it, either in cash after a free trial period or spam. WinRAR is popular in Europe and whilst some sites claim free downloads, there is usually a catch but at least it always works for me and that's unusual. https://www.google.com.au/url?sa=t&...eiqXICGuQIHmdpDFgRElpw&bvm=bv.116274245,d.dGo
hi Miklos,
thanks a lot for the link, it works perfectly.
the problem seems to be at front end amplifier. most of the jfets are not available in the real market.
but any way if is ok I can post the schematics some where all can see it.
Cheers,
Williams
