   Hi fedi, I need a replacement adapter for my keyboard. It has a 12V connector but the original brick has the following specs:
   DC12V 16VA 700mA
   
   ...that probably means I can't just buy any type of adapter, right?

     @benis@cawfee.club so something like 1000mA would be fine even though the original was 700mA? I seem to have thrown the old power supply away when I moved here it seems so no luck with that :( The keyboard itself just says "rated for 12V, AC power adaptor: yamaha PA-3C", but that adapter is no longer for sale it would seem.

     @dwarf as long as the plug size AND POLARITY* is maintained, the output voltage is the same, and it supplies at least the rated current, anything will do
     
     *most daily stuff takes a center positive supply, but most music gear uses center negative supplies. check the label on your current PSU to make sure

     @dwarf correct- you want to match both the power specifications and the barrel plug size (if it's that type). The original brick should have a manufacturer and model number on it, you can search on that for replacements of the same brand or equivalent replacements.

     @chillicampari@layer8.space it seems to be out of stock pretty much everywhere online, but it does take batteries... I'm screwed :blobcatMelt:

     @dwarf ugh, I just ran into that with an external DAC with a less common sized barrel plug, but luckily we found something that matched (and still seems to be working, fingers crossed). I hope you find it in stock soon (or a replacement)

     @dwarf @benis

     You want the current to be at least what it originally had (700mA) but having more available (1000mA) won't be a problem. It just won't use it. And hopefully the keyboard has protections inside in case something shorts and tries to use more than 700mA.

     @dwarf the pictures of it I could find show that it's a center positive PSU so you're going to have an easy time finding a replacement, you just need to find one that physically fits
     
     Yeah, 1000mA (1A) would do fine, because current is a consequence of voltage. A healthy circuit is never going to pull too much current.

     Thanks for all the help guys! I found a 1A adaptor and it's working just fine! :blobtoofast:

     I am much worse at playing keyboard than I used to be. And I used to be... quite shit.
