Glad to see that you got another board to experiment with. It is good to have one spare! About the regs from that china guy, that is too much money spent for me, this mod cost me already bunch of money, and don't wanna spent extra. Instead i am going to search for alternative replacement of the reg if they are really faulty. But thanks anyway. And i just discovered that the pod freezing even without any signal put in. Just switched on!!! And the system make that little "pop" sound when switching on, even at volume set to 0, and without any cable plugged in the pod. Is this normal? I don't remember, be like that before(i mean before all mods i have made) Unfortunately, left the multymetter in work, and can't measure if the regs put correct voltage. @ramachandra said i can use L7818CV and L7918CV , but they are pulling 1A out, not 500mA like originals. I wonder if that would be a problem? I can order exact model for positive, but negative one is really hard to find even L7918CV!
