Otari MTR-12/10 power code plug for 240V mains

[Mo-Tech]

I have Otari MTR-12 (very similar to MTR-10) that has mains rated to 220V. My mains are 240V so I think it runs little stressed hence I'm using APC converter. I re-capped most of the machine and found MTR-12/10s are probably all made with universal power-transformer boards with a coded plug, a simple 12-pin socket to switch it to whatever mains. Probably to swich it from the standard 100, 120, 220, 230, 240 or 250V, all 50Hz or 60Hz. I'm guessing it just needs the pins re-routed.

In case anyone needs a 220V mod, here's the pic of the 220V code plug:



That's the plug (it's easily visible from the back of machine w/o removing the board like I did)



220V plug has pins 3 to 10 connected:



For 120V it's pins 5 to 6, 9 to 12, found this info here.

Does anyone have a 240V rated Otari MTR-10 or MTR-12? I'd buy a decent beer to who bothers to remove two little screws on the back power panel and see inside what pins are connected for their 240V mains, I will not need to run converter then.

Hopefully we can "crack" those the MTR-10/12 mains codes.
