Thank you for your feedback.
Would it be ok to send you pictures of the boards with components and soldering for some feedback?

Typically that resistor will blow if a 2A3 is plugged into the socket without care as to where the fat pins go. If you push hard enough, the fat pins can be forced into the skinny holes.
