CR-620 stuck in protection

Parts for the board arrived and I changed out TR701-722 (except 707-708) so far but no change to the distortion yet. Still getting 40 V on the emitters of TR719-720. Anything else to focus on here? I will be taking a more in-depth look tomorrow, also to check relay contacts for dirtiness.
 
Reflow ALL your solder connections on this board before changing more parts. There’s a very good chance you have a bad solder joint or crack in a trace somewhere. With old amps, the problem is almost always physical unless something bad was done to the unit to damage it electrically.
 
Thanks @Sparkplug, appreciate your feedback. I ended up suspecting the output transistors I bought on eBay and replaced with some from Mouser per another AK thread. This fixed the problem completely. I will continue the recap. Very clean sound from this unit.
