Nothing stopping you from using two smaller transformers - 120 primary 
to some secondary voltage, say 24VAC, then a second transformer with a 
240V CT primary that also has a 24VAC secondary. Assuming you get the VA 
figured out correctly these should work and be much smaller than a 
single 240CT to 120VAC transformer.

Hammond Manufacturing makes a wide range of superior quality 
transformers that is widely used by the tube and regular electronics folk.

I think you will find this series helpful, note the VA rating and get 
yourself one of the 187C20 and a 186C20 - or for a bit extra power and 
to allow for losses, get the 187D20 and 186D20 - wire the 24VAC 
secondaries together (ignoring the centre tap on the secondaries of 
course). Farily compact.

Hammond also will wind you a single or a thousand transformers...I like 
looking at their complete line, including a replacement transformer for 
the early 1920s RCA Radiola III battery radio.

Amazing range!
