Cheap option, check one thing first

12V center-positive adapter

12V DC, center positive, at least 0.7A (the X-12 is rated 8W). Plug size not confirmed.

The manual gives voltage and polarity, so only the plug size stands between you and a stock adapter.

Check first: Measure the jack or old plug, because the barrel size isn't published.

The usual mistake

Reaching for a modern Fostex AD-15 series adapter; those are 15 V and nothing ties them to the X-12.
