Found the problem, I did swap Q8 & Q9.Hi fellow DIY'ers,
Just finished a Rev F build. This is my third Hairball FET/Rack build, the first two went all smooth but on this one I'm having trouble.
When I turn it on the 75R 3W (R84) resistor in the power supply turns smoking hot after a few seconds. Obviously something is drawing way to much current. What have I done so far?
Checked all the components if they are the correct values - should be good on that
Checked the polarity on all electrolytic caps - good
At this point I'm a bit lost and I would very much appreciate it if someone that maybe had a similar issue before or someone that has an idea on where to look could chime in and point me in the direction on where to look next.
If it wasn't all on a pcb board I would disconnect the gain reduction or the signal path but since that is not an option I'm hoping for someone with a good idea on how to proceed without desoldering all the components.
Help is very much appreciated.
Stupid mistake that brings a lot of problems.
