Hi Adam, Yes, this looks pretty decent, the schematics (p.1) as well as the selected varistor which is a nice component and perfectly suited to replace the 47pF. :-)
As there's always sth to improve :-) I suggest: cut J1:3<->2, connect J1:3<->1 cut J1:5<->4, connect J1:5<->1 rationale: connect unused input to GND -> less noise cut connection and insert a 100R, from joint C19*R17 <-100R-> J2:2,3 cut connection and insert a 100R, from joint C21*R18 <-100R-> J2:4,5 Rationale: some protection for LineOut amp / internal clamp diodes there consider 2pin with jumper to GND for TP50 rationale: again noise of unused input consider make J23 a 4 pin: 1:AUDIO_AGND 2:CD_L 3:CD_R 4:CD_GND Rationale: convenient variety of input configs, at least possibility to short CD_GND to AUDIO_AGND for common-GND design setup Good job, kudos /jOERG _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkymist@Freenode
