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:
https://www.amazon.com/Adapter-Transformer-Doorbell-Tyrone-Compatible/dp/B081JQV8PL/ref=sr_1_12?dchild=1&keywords=18vac%2Btransformer&qid=1586884487&sr=8-12&th=1 (https://www.amazon.com/Adapter-Transformer-Doorbell-Tyrone-Compatible/dp/B081JQV8PL/ref=sr_1_12?dchild=1&keywords=18vac%2Btransformer&qid=1586884487&sr=8-12&th=1)
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.
Or...

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 8).
