The value of the amp has nothing to do with what parts cost.
If you can get another bandit 65 for 50 bucks, buy it and use it for parts. You probably won't find an adequate transformer for that price.
Sorry if that sounds harsh, but that is the reality of parts costs.
You need a power transformer that puts out 60V center-tapped (30-0-30) good for at least 120VA. If it's not the exact peavey unit, you will have to drill and cut to make it physically fit the chassis.
