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. https://www.hammfg.com/electronics/transformers/power/186-187 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. https://www.hammfg.com/electronics/transformers/classic/118944 Amazing range! https://www.hammfg.com/electronics/transformers/classic/zone John :-#)# -- John's Jukes Ltd. 2343 Main St., Vancouver, BC, Canada V5T 3C9 Call (604)872-5757 or Fax 872-2010 (Pinballs, Jukes, VideoGames) www.flippers.com "Old pinballers never die, they just flip out"
