In that case, you are in great steads.

Considder that you can use a much smaller transformer to drop a few
volts. I think Jon had posted a pic or drawing a week or two about that.

Your simple 100VA doorbell transformer with both primary and secondary
grounds tied together, and the primary comes in, the secondary goes
out and it drops some few volts. not much, so the wattages is small.

Then you can use those great value units !
