I was once thinking of using a transformer that had a secondary
voltage of 36VAC and use pass transistors I had in my spare box. I
wanted to use a T0-220 case NPN and the design required the use of 8
of them in order to lower the heat dissapation per transistor. That
changed my mind and ended up usign a different transformer.

Usually, transformers can be found more reasonably priced than
semiconductors of high current ratings, especially surplus!
