New to the site. Great to see the DC community alive & kicking.

Ok I have an old DC I've unearthed from my cellar, ,, My eldest is currently into old retro games consoles, already nicked my PS1 PS2 PSV NDS Wii ect of me now I've got my old DC (HTK-3010 / 670-13624A) JAP version,

I am from the UK when I bought it, it came with a stepdown adapter for 240v to 110v worked great,
Now I've dug it out & cleaned it I'm unsure of the Voltage adapter after all these years to be safe, I'm not keen on spending money on new PSU's Pico ect ,so I researched the original PSU (DC is near mint condition under the hood).

PSU looks fine caps pcb, I've searched the apes of it & found nothing related to region Volt but as I see the input part it sates on pcb..

AC250V 1.6A
85VAC-132VAC 50HZ/60HZ

My Question is woul a normal 8 plug with UK 240v work ok or would I need to still use a stepdown to 110v?

I'll be puttin me son onto the forum soon as I get the DC to work,
It'd be a shame I got a shed load of accessories Arcade pad Gun Rod UK modem plus lots of pads.
I was a old DC gamer made my own HB discs emu cdi vids..

TIA DUZLA+

do not plug it into a 240V socket, your power supply will burn out, and the capacitor may even explode.

You have to use a stepdown transformer as the DC does not have a universal power supply.

Having said that, there is a mod you can do on some of the early Japanese DC PSU's to effectively make it 240v compatible, but I've never done it and don't know it's validity.

If you try this mod, as always, when working with power supplies of any kind, do so at your own risk. Be careful as caps can still give you a shock even when unplugged.

Just did psu mod on my jap dreamcast (launch model) to 240v, need to replace one cap and one resistor that's it, easy mod if you have basics in soldering.
