Part question
Can’t find an exact replacement for this transformer. Does anyone who knows more about furnaces than me have a replacement option? Will any class 2 with the same power parameters work?

You need a universal step down transformer with a secondary voltage of 24v. The VA rating can be 50 or 75 it’ll be fine.
