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

Anyone who works on your amp will want the circuit schematic so they can test voltages. You should contact Anthem (new owner of SF) and ask for a copy. It's usually standard practice to release schematics when a product is out of production. Anthem has been good about doing this in the past.

Best of luck in your efforts.
