At the surplus store, I found a power supply over 20V, but it was higher than ideal. The supply was probably from an old printer and it was 32 volts. This odd voltage should be safe for the electromagnets in short intervals. I should not need to energize them longer than a few milliseconds at a time.

Testing showed that I was able to move a key with a short button press and not start the solenoid on fire. There was magnetic pull to move the key from a resting position to a striking position fast enough to hit the bar and make a sound. I may have to put a small pad on the magnet or key to silence the strike there. This should not effect the glockenspiel's sound.
