From Graph Paper to PC Board
Using the coordinates from the graph paper for the 6BA6 Audio Amp, the data was entered into Carbide Create. The next two steps were the generation of the G-Code saved as a text file. This then resulted in the milling of the PC Board.
Now that was the easy one as it only involved but a few squares. The actual Regen contains more parts, and the layout is more critical.

For those following along and use the super glue and Manhattan Pads, all of the Grid Squares are 1/4 inch. So yes, you will have to count squares, but this gives the location of the pads. The open space on the right side is for the large choke AKA small audio plate transformer where the primary side is used.
I have the G Code but didn't get a chance to cut the board which is 4X6. I made the pads a bit bigger to allow for cut material. The next posting will have the cut board.
An experimental element will be the coil. I am planning on a 3/4-inch HD PVC pipe for the form which will mean more turns as the W3IRZ design used a 1.25-inch design. Ascertaining the tap point is like access to the 1st set of knickers and will involve experimentation.
Them that don't know sure wished they did! I guess there is a lot of that in our Nation's capital.
