RE: In my direct-coupled 45 amp....some observations

Posted by mah on March 11, 2017 at 17:41:26:

Jeff, simply by observation and knowledge/experience in such things.

I see blobs on tube-socket terminals, blobs/balls else-ware, excessive solder wicking along wire, dull masses of solder on multiple-component terminations, and the terminations on the rats-nests of component leads, e.g. chassis RHS/above centreline is very poor practice and likely
to have dry-joints.

Attached is a solder joint inspection guide and also a pic showing good soldering work.

I hope you find this helpful.
