Hi all,
Just finished putting together my 1st nava build and having some issues, any pointers would be much appreciated...
PSU board all ok +15/5v ok and -15 ok.
once connected to the main pcb and measured connected, the +/- 15 sits at
1. the noise circuit:
IC 27 getting +/-1.5v on pins 4&8
IC32/33 getting 1v on pins instead of 15v
noise noise output
have checked for dry joints, component values and diodes
2. master: 0.8v on tp1no variation to allow 5v
sequencer runs and allows epson init.etc
plus display dim
no sound out for any voice
any suggestion?
thanks
