[Boatanchors] audio transformer

[J. Forster]

The filament transformer will have slightly more eddy current (core)loss
at high frequencies due to the thicker laminations, but this is usually
immaterial.

>> Maybe a small filament transformer:
>>
>> 8:600 is about 1:75 impedance ratio, so the turns ratio is SQR(75) =
>> SQR(3) x 5 = 1.73 x 5 = about 8.2:1
>>
>> The turns ratio of a 12 V filament transformer is 120/12 = 10:1
>>
>> Close enough. I'd try something small like 12V @ .25 to 1.0 Amp.
