Performance loss in used amplifiers?

I own the 'boat-anchor' called White Audio Labs A100. I don't know how old it is but it has a blown transformer for 1 ch. The place that diagnosed the prob.says both trannies should be replaced. Where does one get these? and, how much for the parts and r&r labor?? Transformers R-us?? duh?

Hey;--Thanks for the help, Marakanetz---I will see what they can do for me. Looking for Randy White seems a lost cause. My experience has led me to stay away from older SS amps.
