I am working on my 90 with PP 45's.  All seems good but it looks like the 2.5 filament section for the 24 and 27 tubes is shorting out (section A).  My question is, can I just get a filament transformer rated at 2.5CT 10amps and wire it in as a replacement, or do I need to try and find a complete transformer.  The Philco part# is 4938 and I do not think it was used in any other models. 

Transformer I am looking at http://www.mouser.com/ProductDetail/Hamm...2EniHK8%3d
