18V AC Adapter

[Timko]

For the DE Fx's Mutron Biphase project, I need an 18V AC power supply.  After trying to figure out the correct search terms, it appears the Ring doorbells use these:

However, they all come with leads exposed instead of an adapter.  When wiring an AC adapter, there's no ground/power connections.  You would just connect the two wires from a barrel adapter to the power supply and be done with it, correct?  I'm pretty sure this is correct but wanted to check before I ordered something that would fry my build.

Correct. There's no polarity with AC, so connect the wires to which ever lug on the plug you wish.

It was the $11 in shipping that I was trying to avoid.  I'll keep looking through Amazon to see if I can find an adapter with the barrel on it.

Dang! I gotta get one for the Hapalochlaena. $25 for a power supply stings. I like your DIY spirit though.

I'm already getting a broken Wah to turn into a 1M-B expression pedal for this build, so I may as well wire my own power supply too  .
