+48 v and 5 v indicator lights - AMEK BIG 44

Postby swor27 » Thu Jul 28, 2016 10:57 pm

I have a 401 PSU for the BIG 44 and all 6 lights are on on the PSU showing it is fully functioning (in theory) but the +48v and 5v lights on the meter bridge are not lit (the +V and -V lights are working). Is there something I'm missing either in the PSU or in the desk (internal fuse on desk)? None of my channels are working as they should... I can't confirm there isn't another problem with the desk as I've not had it up and totally running yet. Just wondering if anyone has run across this and could save me some time probeing/troubleshooting. Thanks

I can't help with the AMEK 401 power supply, but the guys at GRS work on these PSU units all the time.

Here's their email: info@grssystems.com

Hope you get it going!

Yeah I know they make a super beefed up PSU. Would love to go that route but it's a bit pricy right now... Thanks Greg.

No, I meant...talk to them about working on your AMEK 401, not getting a new one.

Before I had them build me a linear PSU, they used to service my AMEK 401 PSU.
