Hi group,
I have completed the assembly of the thru-hole version. Here is a picture of the assembled board:

If you are trying to read the colour codes, most of the resistors used are 1 or 2% so they have an extra band.
I also substituted a 3.3 Ohm resistor for R10, because I didn't have any 3.0 Ohms.
Here is a photograph of the board being tested:

I have the board hooked to a General Radio Decade box, out of camera, set to 1 Ohm.
I needed a 12k Ohm resistor in R24 position.
