Solid state with output traffo?

    I've been sniffing around eBay for a while, hoping to buy big ol' broken power amp to repurpose its case.

    Recently I saw a commercial (PA, or similar) Phillips. Not too many details, so I GIS'd the model name.

    One of the things I found was a slightly different model, with TWO big toroidals, mounted in a very assymmetrical fashion, which struck me as odd for a stereo amp. Looking at the back panel, with output sockets stated for various voltages, I looked again the right hand (as seen from the front) traffo.

    As far as I can reckon, it's an impedance matching output transformer, albeit that the output is specified in volts, not ohms.

    (It also has a 135-alike-fan-assisted-heatsink-tunnel)

    It's a 100V line jobbie for PA use.
