hello
way too many projects and in the confusion I Fu%¤#"7D up:
by mistake I swapped c3 and c4 with c13 and c14
discovered the mistake before powering up when comparing with another unit just assembled and soldered out the parts and swapped back
BUT had some problems with tracks on pcb : couldn´t get pins properly through and just soldered on top
result is reduced lvl in right channel
have I lost one halv of the differential signal
using balanced out
any clue which component may be without connection to cause this fault?
could buy a new pcb at 19usd, but you guys are closed for 2 weeks, so I´d rather solve it now
best
Leif

hello
what about putting the schematic on th IVY page with the manual and the BOM?
It´s dificult to see anything from the traces
If I had the schematic, I could just ohm the circuit and find the missing connection

hello folks
happy ending:d/
after some measuring around I found out that R4 wasn´t soldered in one end
no wonder I lacked half the signal
best
