I never under stood why people think a switcher is better than a linear
power supply.
I guess I just like to keep a classic original and not hack up the wiring
harness. I have 3 star trek games and have never had a problem from the
power supply's. I have seen a few that had problems with the inline pins having
bad contacts and burning up but just replace the pins and plugs and their
good as new.
It can and has been done so good luck.

All,
I’m about 1/2 the way through my modernizing of the G-80 PSU board in the
Sega Vector machines.
I’ve already designed and laid out the 5V/4A and 12V/3A Switcher; I’m now
going to focus on the negative voltages and soon the audio amplifier.
I believe the 5V and 12V switchers have a lot more head room than quoted
above – but I need to do some bench top testing once I have a PCB back from
batchpcb.
My desire is to replaced the discreet transistor amp w/ a more modern
monolithic IC – proally from Maxim.
Anyone have any clue what the specs on the transistor amp are? Wattage?
The plan is to “donate” the PSU design to the community under the open
hardware TAPR license once it’s validated and functional.
