Looking for ADM-3A power transformer

[John Parsons <jpars...@gmail.com>]

I have a well-working ADM-3a that I got from eBay.  Unfortunately it is a 220V version of the ADM-3A. I am using a 220-110V step-down transformer, but would really like to have a 110 V transformer for the ADM-3A. 

The original 110V transformer part number is 129458-3. It has 3 windings: 9.4V used for +5, 31V used for +/-12 and 20.5V used for +15. I can't find any current ratings.

Anyone got a scrap ADM-3A for parts? I am willing to trade money for parts, or trade a 220 v transformer for a 110 volt one! Other ideas?
