[AMRadio] Transformer help

[russ dworakowski]

Gary,  if  you  infact  need the  240volts  on  the  primary,  you  will 
then  get  double  the voltage  on  the  secondary.  The  limiting  
factor[smoke]  would  be  the  current draw-  in other  words
how  much  current  [load  on  the  secondary].  Remember,  you  are not  
getting  something  for free.  You  can  estimate to some degree
as  to  the  power  handling ability  by  size.  Older  transformers  were 
larger for  the same  amount  of  wattage  as  compared to newer
replacements.    Do  you  have any  specs?  Russ
