Hi Cbird,

I don't recognise the part number - is this the filament / HV transformer, or the B+?

The Subtronics (just like the Talema and Avel Lindberg) transformers were custom made for Atma-Sphere. I can check if we have any of the old M-50 Subtronics parts laying around, but I don't think the odds are too good.

If it's the B+ part that is bad, you'd be best off buying a pair of current M-60 transformers, and retrofitting each amp. It's really not all that difficult. If it's the filament / HV part, that can be replaced with seperate 6.3V and HV transformers. You might be able to find an off-the-shelf 6.3 @ 20A part, but you will want to order the HV part from Atma-Sphere.

Hope that helps, Bill.
