Yamaha XR258 - Newbie assistance

[duke2k7]

Hey guys,

Just took the psu outta my JPN model 2, but nowhere can I see whether this is 3.3 or 5 volts. The DragonCity psu I have installed has two power options.

Can anyone say for sure what voltage to set the psu to? I’ve checked online on a lot of pages but the only info I can glean is the capacitor list for the psu and not it’s voltage

I guess I could leave it at 3.3 and see if it works, if not then I know it’s 5v, but I thought some of you might know before I do something stoopid lol

Thanks

Yamaha XR258 (Model: 35M07U) is type B according to my notes, pinout is GND GND 3.3V 5V 9V on all such PSUs.

When in doubt, check it with a multimeter.

Normally, the multimeter is the first thing out but we've recently moved and have no idea where it is lol!

So on the pico replacement, there is a switch that basically offers 3.3 or 5 volts. I'll try 3.3 and see what occurs as that was my original query, but those pinouts are mega useful, thanks!
