Spent some time with the drill and a blank L bracket today and got everything wired up.The unit I currently have working is about -6db on the output... after reviewing the Harrison Ford Filter schematic again, normally, the HFF circuit uses an INA134 (0db line receiver) and DRV134 (+6db line driver), so leaving the DRV134 out of the circuit (taking unbalanced) and using a -6db THAT 1246 would leave a -12db signal feeding the discrete voltage follower buffer, not the -6db I was expecting. Putting a 1240 in it's place should keep the overall circuit at unity gain.I'm just glad it works, and it sounds pretty damn good too. I'll need to listen to it again once the euphoria over the fact that it actually worked subsides, though... But so far, minus the line receiver issue above, everything is working exactly as expected! Which is odd, because I honestly have no idea what I'm doing...
