Hi!
Trying to understand why this supply behaves like it does and here is some info:
* My -20 rail works for about 3-4 months, then a couple of 2N5886 is blown, I change them and then it works again, never any other rail breaks
* The -20 led is lit not as bright as the others and this is something that gets worse and worse, after last repair its even more faint (with also no load on supply)
* reuglator cards is checked and even switched out the -20 card but same same
* resistors in the -20 rail is checked and 2 was replaced when last serviced
I simply cant find any issues, the bridge rectifiers is hot, -20 more so than +, they are moved since ages up from the "railboard" and fitted in the chassi on the top chassi sides
Im not an electrician but managed fixing things having this console for 15 years . Can a bridge rectifier wore out and need replacement, ot is it working or not? Some tips of what to check?
