Today, I went to a shop to buy a step down convertor.
Then I could test the new cab with an old us power cable.

and ....
Absolutly nothing. no picture, nothing.

I check the voltage on the monitor and ok 115 V and behind the marquee ok 115 V too.
the monitor is dead

I do not have spare for the 115V bulb, -- > 220 V for testing

Let's go to my basement to retrieve a NOS monitor that I got a few years ago.

the old monitor removed

Burn with galaga AND Qix

it's a POLO , I must make some changes to put in the galaga cab.


Ready to test


In the cab



I check the pinout of the amp's connector from the PCB to monitor

AMP 6
1 Red
2 Green
3 Blue
4 Sync H & V
5. Ground

AMP 3

The new Monitor has the amp universal 6 connector but with separate sync and no AMP 3 12V to the video PCB.
Here is the status with ; no separate Sync and no 12V to the PCB video.
