Did the Mr Bill mods to a White's Classic III

It's not pretty, but it works well. I was impressed with the results and versatility of the Classic ID I did this to some time back and had the components it do it so I figured why not.
Can't wait to take it out for a go. Impressed with the air tests.

It's better to replace R7 with a 200 ohms trimmer or so instead of the 51 ohms resistor he suggested. This way, with an oscilloscope, you get the best amplitude possible.

It would be good, if all pot wires are twisted, and wires of GB pot are shielded...
