Christmas tree power supply help!

So my parents' old fiber-optic Christmas tree had a minor wiring issue and melted the connector on the power supply. The power supply has a 12VAC, 4600mA output, which is really hard to find 2 days before Christmas. Does it really need that much current? Is there a way to replace just the connector (12v/55vA)? I have a basic understanding of electrical wiring and have done soldering and crimped new wire connections before. I just don't know where to look for supplies on such short notice.

Welcome to the forums.

If that is a 12 VAC/55va power supply..... give it a try.

12v x 4.6A = 55watts or va.

If you can find another that is 12V and greater than 4600mA, you'll be fine. Just don't use one rated for less than 4600mA. In other words, 4600 mA is the maximum current that supply can deliver, so if you can find a replacement that can deliver at least that much, it will be fine.

Many of those fiber optic Christmas trees have a halogen light inside. How much current it actually needs depends a lot on the size of bulb. So it is possible it draw a fair bit of current.

When shopping for a power supply make sure you get one that outputs 12 VAC. Most electronics need a DC power supply but yours must be AC which is required for the motor that drives the color wheel.
