M-70 Protection Circuit

I have an M-70 I purchased on ebay a month ago. It worked fine and sounded good at any volume for about 3 weeks. Now, no matter what the volume, the protection circuit randomly comes on for a second or so and then goes back off. It does not matter how long the amp has been on. Any ides?
 
Probably a cracked or cold solder connection. Check the DC offset after the amp has been on for 10-15 min.
