Thanks for the prompt attention Joe!
C1 and C2 are the pump charge caps for the 48v rail. They will only puff up if the power secondary transformer AC voltage is to high or there is a dead short on the 48v rail or the doubler/tripler jumper is set wrong. What power transformer are you using and what is its output voltages? What have you got the tripler/doubler strap set to? IS this a full JLM powerstation kit of parts with our 1000uF 50v caps?
-Ok, starting to make sense. The transformer I'm using is an Avel-Lindberg toroid 115V 2x primary 12V 2x secondaries. I have the secondaries wired in series which is coming in around 28.1V~.
This is a complete JLM powerstation, using the 6A rectifier, omitting D1-D4, C8, C9, C10, both LM337 and neg side parts. I have a jumper between the pads of C10.
well this is embarrassing, I have completely neglected to install a jumper in either doubler/tripler section. Seeing now I need to install a jumper from the center pad to doubler. (this also explains why I'm only able to dial in the available 31.5V for the 48V rail
)
edit: needed it to be on tripler, doubler only gets me around 36V at the input leg of the LM317. Learning as I go.
Ok that is fine if there are no shorts in the build.
After seeing the one LED go, I'm not so sure I don't have a short at that specific gobetween, or perhaps I flipped the legs and reverse biased the LED causing it to go out. I will need to investigate this further.
Are the leds soldered directly across the top two legs of the 48v toggle switch with long leg closest to the edge of the PCB?
Yes, I tried to solder them exactly how the diagram shows on the JLM shop website.
Do you get zero ohms between all audio 0v and GO between 0v points and XLR pins 1's? Are the in and out XLR wired mirror image of each other?
I will determine this after a more extensive investigation.
Answer above questions and I should be able to get you sorted and send any photo's of your wiring and powerstation PCB top and bottom to my email address.
I will snap some photos as I go.
Powerstation Schematic is in the first post of this thread with the full build and setup instructions. If you have trouble downloading the PDF's read the first thread on the kit forum.
Yes, I had a blank page open but wouldn't load a schematic... I'll look around on kit forum, thanks! edit: I was able to download the schematic, thanks!!
