Elekit 879S Modification

My amp that I built years ago periodically crackles or makes other noises. I want to open it up and touch up the soldering.

It would be fun to upgrade or change since I am in doing the work. Any ideas with instruction would be helpful. Any ideas on things to check would be great also.

Thanks.
