Aleph-X diff pair trouble?
I've build an Aleph-X and am having some trouble with one side (using rev. 1.0 board, low power Grey's design, options: D1a, J1a, jumper on Q12a, r48 and r49). The voltage over r25 seems ok (around 4V) while over r23 its over 6V. I've already changed the diff pair but to no avail. Also I noticed that R1-4 and R42-45 are heating up excessively.
Any ideas what could be the problem here?
some of us aren't so informed about exact pcbs and schm version
fill that blanks (schm , pcb graphic info , pics of your exact work) here and maybe someone will be able to help
Late night build and post is a recipe for disaster. I've checked wiring 20 or so times and final it bit me in the ***, swapped the gate and source of one of the output MOSFET's... fixed it and voila: SOUND:bigeyes:
Thanks for the post anyways!
