Try http://www.pwdahl.com/ if you haven’t tried them yet. I’ve ordered many good chokes and transformers from them.

Subject: [CRTech] Looking for a BE FM-25T (not A nor B) Filament Transformer
We are trying to locate a filament transformer VR-203 Part Number: 217-224-9617 for a BE FM_25T transmitter (not the A nor B models).
BE does not have any in stock and is not certain when they will have them in stock again.
If you are aware of any – even connected with a used transmitter for sale, please contact me off-list at: firstname.lastname@example.org
