close to completing the ppa, but the volume is only moderate when it's maxed out. unless my hearing is worse than i thought, this doesn't seem normal.

my r4 is 10k.

You are right, that is not normal.
Picts?

values for resistors used are as follows:

R14.32K

R2,R61M

R3, R9,
R11-R141K

R4, R710K

R53.32K

R810

RLED2.21K

sound seems to distort at high volumes, bass in particular.

Have you seen my troubleshooting article?

should'nt have returned the dmm so quickly. oh well, i am going to have to wait a week or so to use the school lab.

anyways, i was playing around with the wiring and noticed when i only have one of the input wire plugged in i still get sound on both earpiece.

Could be a wiring problem, or a grounding problem.
