Hi Emo,
wish me welcome, this is my first post in this forum.
I was also looking at building my own power supply for pelts. These transformers are the bests I could find. They don't fit exactly your need, sorry. Just trying to help:
12.6V, 25Amps (good for 16V pelts)
24V 8Amps (it will yield more than 24V DC after rectification).
and many others in this link:
All Electronic surplus
Good prices too.
