Hi MrAl,
Good to talk to you again…hope all is well.
Now I'll put on my technical hat for a moment.
From your attachment directly above I see the following:
1. The input, pin #3, is correctly connected to the bridge and filter cap;
2. The output, pin #2, is incorrectly connected to the voltage adj circuit, the junction of R2 & VR1, vice the correct termination to the junction of R2, R3, C3 & CN2 (out);
3. The adj, pin #1, is incorrectly connected to the junction of R2, R3, C3 & CN2 (out), vice the correct termination to the junction of R2 & VR1;
4. The regulator, LM317T, can be mounted on the board in four different positions, all of which would be incorrect based on the existing board layout;
5. From the OP's post #7, the silkscreen is on the component side as shown in the second graphic of that post;
6. The initial placement of D2, cathode to the bridge and anode to the output, was correct, but now the anode is not connected to the output of the board.
7. D3 is correctly placed in the OP's post #12 IF the pinout of the regulator were correct, however, the placement and polarity shown above appears incorrect given any configuration of the 317.
My conclusion is the OP may have chosen the wrong component from the library during layout. The 78xx family of regulators would match the input, "common" and output pinout in the layout. I'm thinking maybe the OP may have assumed an identical pinout between the 78xx family and the LM317. Just guessing at this point, but it may be the root cause. What are your thoughts?
Cheers,
Merv
