[Amps] Filament Transformer?

[Mike Wetzel]

My old Raytrack HF amplifier DX2000L (pair 3-500z's) filament transformer
(5VAC @ 30amps plus a 12VAC relay power (low current)) bit the dust.  By
some strange chance does anybody have any idea where to get a replacement
the exact same size (tight fit)?  I have a quote from Dahl and just
wondering if there are any other options.  I had sold the amp and the
transformer went up in smoke when the new owner turned it on so now it's my
problem.
