Hey Perry,
I just finished building a 500m back from the grave. The amp working almost perfect except the amp will not shut off with remote power removed. Have you seen this issue before I swap out the lm339?

Q4 drives 5v to pin 4 of the 494 to shut the amp down.
Are pin 1,2 and 13 of the 339 going low when remote voltage is removed?
