check that your PSU is still modified with other regulators

my psu was still modified with the correct parts

just a visible check and keep in mind to test the psu later without attached Device/pcbsPatrick

325.Jan 2024build infoVoice and Voice Motherboard

you have to respect that the MOLEX connectors on the Voice Motherboard and Voices have to installed in one step.

You cannot start with soldering the molex connectors at the pcb without align it against the opposite part.

do this: 

option 1:

  1. mark every voice card with a number which match with the voice motherboard slot number
    1. insert the Molex pinheaders in the voice motherboard slot 1 without soldering it
    2. insert in voice 1 the molex connector and solder only one middle pin per connector, correct the alignment If required
    3. insert voice 1 in voice motherboard1 and solder one pin on the voice mobo Molex connector.
    4. check and align - solder more pins.

option 2:

a.  insert in voice 1 the molex connector and solder only one middle pin per connector, correct the alignment If required

b. insert in the connector the connector  which is required for the voice mobo.

c. put the voice to slot 1 and solder it - one pin per connector

d. check, align and solder more pins
