Re: deltapuls
"Tr" ist a test point and at the same time a net label. All test points and net labels with the same name have a connection like Tr5 (PIN10 IC D3B and PIN12 IC D9B).

I think these are convenient test points for checking signals with your scope. For example TR3 would be the signal used to turn on the FET which energizes the coil. TR1 is the output of the front end amplifier. Tr4 and Tr5 are timing signals use to gate the 4066 switches. The reason Chris calls them Nets is that they also serve to show on the schematic that they connect over to the switch or gate input to the 4066 chip as well. Those are kind of dual purpose in that respect. Let us know if you build it. I'd be interested in how it performs.
Good luck,
