Hi Folks, Later this week I am going to slowly start up an R-390/URR that I recently purchased. After careful visual inspection and removal of several of the modules, I am confident enough to start it slowly on a variac.
My question is, what provides the typical 'filtering' of the rectified DC voltage? Is this C101 (the large rectangular metal box capacitor next to the power supply)? What does the other large, cylindrical capacitor C103 do? Are these capacitors failure prone? Should I expect the need to replace them? Thanks, -Alex ______________________________________________________________ R-390 mailing list Home: http://mailman.qth.net/mailman/listinfo/r-390 Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
