350-0004-0 is the part number for the transformer conversion kit (new bottom panel, transformer and hardware). Last I knew it's list price was $130 + shipping.
I have a .pdf file of the conversion instructions if you want to PM me an email address.
Email or call: firstname.lastname@example.org
or (209) 234-7300 extension 120. 9am to 4pm PST USA.
The original EI transformer was a special wind, not an "off the shelf".
Hope this helps.
