I'd like to add a little more info from the troubleshooting I've just completed.
IC5 is still removed.
With IC2 removed, current draw = 0ma. -- I trust this means that my issue lies with something on the 5v rail?
IC2 removed and powered by itself is drawing about 3ma and putting out 5v.?
Q7 removed = 0ma.
Q7 removed and bypassed = 900ma
