Hi,
I just finished my sammichSID aswell. Its with the negative green LCD. Initially i had it set to low current on JBL and no shunt on JR4. The display was dim. After voltage checking and installing my 6581's (shunts on both JBP and horizontal on JP) i decided to move to the high power setting after re-reading the emails from WIlba stating the negative green was also high power. i'm using a regulated 2A, 12V non switched adapter which reads 12.15V. I found a post on the forum replied by niLS stating that within 3% of 12V should be ok. The display lit up nice and bright, with the pot set to under halfway, but then dimmed after 10 seconds. now all backlighting is gone. Fried?
regards,
Carlos
