We have had plenty of very useful discussion and help on the dac board, both parts of mod 21, op-amp swaps, better electrolytics, more power supply decoupling etc etc.
But what about the headphone board?
There does not look like enough space to increase the main 2200uF, but the output seems to go through a couple of 10uF 50V (EC1 and 2), maybe change these?
Are MC4 and 5 mylar? they are the zobel on the output? any point in changing these?
What about the 10uF bypass cap on the 386D's?
Is there a better op-amp pin compatible with the 386?
suggestions and discussion welcome :)
