As previous post, the same visit to local recycler, grabbed 2 used step down transformers, 4.5 bucks.
Smaller one -> primary 2x115V, secondary with 2 windings : 15V@0.5A and 9V@1.5A
Bigger one -> primary 2x115V, secondary with 3 windings : 10V@8.3A, 22V@2.7A and 24V@2.7A
What a weird secondary voltage windings at the big one that is made in USA.
