Default Re: Superstar 6900N V6 - Fault with SSB mode

Hi
This is the PSU I am using, it has one advantage, there is no noise on the output that I can detect, and it is well protected for over current.
It has 2 separate outputs of 12 & 14 amps which I have strapped together. I have tested it up to 30 amps, but it will shut down if it detects a short.
We never did suss out how adjust it to set the OP volts. There are two trimmers but they set the output current limit for each supply.
see here, http://www.golbornevintageradio.co.u...d.php?tid=7616

OK here are a few images

As I'm not a member of that forum I was unfortunately not able to view the images, but it is obviously a SMPSU - you're quite lucky it does not generate RF interference, most do to a certain extent.

Edit: I see you added some images in your previous. Very neat build in that new enclosure.

The "Marchwood" PSU was in the June and July 1983 issues of Practical Wireless. There were additional notes on p. 29 of the Sept 1983, and p. 60 of the Nov 1983 issues. If one is seriously interested it might be worth checking for notes or updates in other issues.
