Hi! after testing with different arcade pcbs and CRT TV sets I'm very pleased with this setup so I'd like to share how I configured it.
I'm using these components:
- Corcom 6EQ1 EMI filter
- Ferrite bead (I plan to include more on the DC output)
- Recapped Suzo 42PP0606 (MWP-606)
- KEL connector
- 18 awg for power cables and 22 awg for the other wires
Setting the PSU at 5.05V in the DC output I get proper voltage (>4.98V and <5.05V) at the jamma edge of all monster boards and smallest ones like the MV1B I have tested.
I use a THS7374 RGB Amp for impedance matching configured this way, and setting csync pot to get 800-1200mV (never more than 2V) at pin 11 of the THS7374:
For audio I directly connect two 4ohm speakers connected in series, this is the easier way and I really like how it sounds, specially in boards with the HA13001 amplifier.
For controls I have modified a broken saturn controller removing the IC and soldering the cables (Kynar 30AWG). I use DB15 connectors and a pair of 3 pin molex in order to change the place of the buttons when using a kick harness.
Since I want a second controller and don't want to modify a working saturn controller I have an eye into this: https://www.arcade-projects.com/for...a-saturn-to-neo-geo-controller-adapters.8858/
