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

Might I suggest:
1) Remove tubes and take them to someone that can test them. If they test fine put them back in for now.
2) If tubes are OK, see if you can find a tech/shop that can do some electrical testing to see if they can identify the problem and if it can be fixed on the cheap.
3) Failing the above solves the problem contact Chris Johnson at www.partsconnexion.com for assitance. Great guy and he'll treat you right.

yeah there is a way to see what is going on but you need to call Chris Johnson (partsconnection I think). When I had one and a tube blew he tld me to do something to identify the issue.

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.
