KIT ASSEMBLY INSTRUCTIONS
Step One was purchasing the Kit.
The 8 pin octal tube socket (largest one) is used for the rectifier (5Y3GT) and should be installed first. Orientation is not critical on this socket, however you may want to dry fit the tube in the socket and decide which side of the tube you'd rather see and then orient the socket in that way.
