There are a couple of 1K resistors to 0V that will then connect directly ~ to the amp outputs all the time before the new DC blocking caps you will add back in. But thanks to some recent patches by Mark Brown on andy-tracking, we should keep the amp turned off more often. |> Another question - is a single big capacitor enough, if it is put into |> the ground line instead of having one cap for each of the stereo |> channels?

Currently, it's | unusable as an MP3 player and that's an important use for me (if | I could use it as an MP3 player, I'd carry it with me that much more | often, which would in turn increase my use of it). Lifting the can and meddling with the caps is nontrivial. Somebody did give this plan a go on the list about 6 months ago and reported some success though. But I don't recommend considering it unless you are in an experimental frame of mind and can deal with the fiddling and risk involved. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkmwESIACgkQOjLpvpq7dMrOYwCgg84IEzmPEoGSozNU+2kl7v3R edgAn2war5CTGE2912IvQ0tROeRbtUTB =qFA+ -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
