I needed a high pass filter at 70Hz, so I added a .0022uF mylar cap to the input stage grids my of SE DC breadboard amp.
The circuit uses a 6SN7 with a 1Meg grid leak resistor.
THD @ 1W/1KHz increased by .3%
The caps are cheap and outer foil orientation was easy to determine, not sure if that is the reason why or not.
