coupling cap value selection ????

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

The input impedance of my headphone amp is 50k. A .1 will start a 3 db rolloff at 318hz. Well that kinda singes my hide. There are 2 coupling cacps in this simple circuit. A suggestion by a trained electronics person is to get rid of the input cap and raise the value of the second (output) cap to .47. This will of cource get rid of the input cap effect and lower the 3db point to around 60 hz. This should improve the bass responce. Why such a low value in the first place?? See any problem with this? I can't publish the schematic, I'm double checking this info. Thanks, Tweaker
