I have few problems with my Nava and really have no idea what can be wrong...

First I don't have -15V when connecting main board. Without connection everything is ok so power supply working good. When I'm connecting main board then I have -9,5V and it's dropping and voltage regulator getting warmer. I checked all ICs and transistors and they are soldered in right way.

Second thing is sequencer. Light on 1st step is always shining when i'm using step sequencer.

Maybe someone had similar problems?
Thanks!

you might have a short somewhere on the -15V rail, check it with a magnifier glass if you haven't done it yet.. also try to remove flux.. the board files are available now, so you can follow the traces.

-15V problem is solved. still have problem with sequencer. i see that encoder is working because i can change "shuffle volume" but not always shows 000 value and i can't change it.

ok i see that i need to change eeprom first because i have CAT24M01. i think there's a problem because now i can't save anything.
