Pittsburgh Synth Box not firing up...

So, brand new to Eurorack here - here is my setup. Tiptop uZeus, Mutable Braids, and Peaks, and Pittsburgh Synth Box. First time firing up after assembling into case, Mutable stuff fires up perfectly, Synth Box's LFO light blinks, then nothing at all. I assume that shouldn't be. Had a very hard time finding much in the way of documentation at the Pittsburgh Modular site, whereas Mutable's modules came with very clear instructions. I tried to fire it up a couple more times, and then stopped, fearing I was damaging the unit - or it was damaged already. I have the red stripes matching. Thanks for your patience with the newb question...

Possible power issue? Did you try to disconnect all other modules and just connect the Synth Box?

Thanks Solitud - I did not, but I described the problem to Sweetwater, who contacted Pittsburgh, who apparently either had experienced this before, or have amazing customer service, or both - because they're sending me a new one - no questions asked, free of charge, send theirs back to them when I get the new one. Sounds like mine was faulty out of the box.

I have tried without success to log on/ renew my membership for Muffwiggler but keep getting rejected.

So I am writing this here concerning problems with the Tiptop uZEUS Power Supply and in particular the panel switch.

I have experienced the same problems as other people with regard to intermittent presence of the three LEDs, believing that modules are incorrectly plugged in, especially as I use a combination of Eurorack and Analogue Systems modules.

I think I may have a solution,but need to confirm it in practice:-

Most of the modules I have assembled or purchased ready-built that contain toggle switches, use a nut to tighten the switch body to the front panel. However, the uZEUS power switch has a smooth barrel, and therefore there is some degree of movement which may be causing stress on the solder joints behind the panel.

I will be replacing the switch with a threaded version and will report the results in due course.

Update to uZEUS PWR Switch problems:-

Replaced switches in both uZEUS modules and inserted jumper in each.

All LEDs working correctly with no flicker etc.

Removed jumpers, everything still working correctly.

I have probably never used my Eurorack system more than 100 times, so any wear and tear on the switches could be ignored.

Therefore, I have to conclude that the problem IS caused by mechanical stress on the solder joints caused by the original threadless switches not being anchored to the Front Panel.

Will report in the future if anything changes.
