Welborne labs phono stage needs help, got killed in power surge last night

The cliffnotes version. My phono stage was working perfectly last week. Last night we had a power outage during a thunderstorm (everything was plugged into a pretty nice panamax supressor). I got up this morning and nada, the power supply is outboard and it blows fuses when not connected to the main circut board. Its possible that its unrelated, but end result is the same.

Is there any way to figure out what these transformers specifications are without having a schematic? I am going to email welborne labs about it as well. Its a welborne labs compleat phono stage.

Thanks guys - Evan

It will be a few months before I can afford to fix them anyway I suspect, so that will give me time to research.
