Hi there,
I can not find the mistake I did today while tweaking this reader.
I changed diodes for some BYV28-200 in order to connect some big (10 000µF 50V) power caps. I did not connect yet the big caps.
Also changed many resistors and took care to put the good values, and some other chemi caps (voltage and value respected).
I checked several times but can't find where I got wrong, the reader refuses to start and I even don't get the "standby" red light.
EDIT HERE: Also replaced LM833 by AD8599 (2), OPA2277U (1) and the 4560 by an AD8620.
Would somebody give me a hand with the schematics, or better some pics of the top of the PCB ?
I would really appreciate to get this reader working again, it sounds pretty well.
Thanks a lot.
