Sonic Frontiers - A Score or a Flushing?

I may have scored or I may have flushed $50….

A couple of weeks ago I picked up a Sonic Frontiers Power 2 tube amp at a garage sale for $50.00. It was openly disclosed to me that it did not work and the seller had no idea as to why. So, my question is are there any preliminary tests with a voltage meter (or other instrument) I can use to narrow the problem down?

My hope is that the tubes are bad; my worry is the transformer is bad. But, I don’t know how to make this determination. While I am a handy guy, I am limited in my knowledge of electrical problems. If it is salvageable, I will certainly find a professional to make repairs, but I would really like to make a preliminary determination as locating and lugging it to a shop to tell me
