Well I may have jumped the gun some!
Since you found 18 and 19 swap those and see if when the amp acts up you get a positive 27 volts showing up.
When you do this be sure the slip on connectiors go back on the right way and that the mica insulators are good and then check that the red wire is not shorted to the chassis which would mean that the transistor case is .
