LPG

Is it possible to get a schematic for the full LPG BOARD
I am building 2 on one chassis piggy backing the power from one to the other. It worked fine for 10 minutes then dropped the +15v rail.
without the traces or schematic it's hard to troubleshoot

No. Peter G didn't release it.

If I were building this board, I would draw my own schematic from it. I wouldn't publish a schematic that isn't publicly available, but if you bought the board I feel it's within your rights to understand it.

I see this board is currently available from Modular Addict.

<p>This module is a variation on the Classic Buchla Low Pass Gate module developed by Peter Grenader and release...


The build guide link is broken on modular addict, but you can get the information you need from Elby.

Thanks guys
It turns out that the problem was a bad thru connection at the Molex connector itself
There are traces on both sides of the board and the thru plating was not working or stopped working! I need a right angled header to make sure both sides are adequately soldered to the traces.
DIY can be Magically effortless sometimes and a real enigma the next.
