Need 8ohm : 5K Audio Transformer

[J. Forster]

Power transformers are not designed to handle  a DC bias and may saturate.

If all else fails, try a 6 volt transformer, the kind you might find inside a large power cube or a straight filament transformer. The best match for 5K to 8 ohm impedance is a 25 to 1 voltage ratio. If you chance upon a 5 volt unit, so much the better. Center tapped 6.3 volt filament transformrs are great since the center tap gives you a choice of impedance match. Get one that will handle an amp and you will have plenty of capability. Your 6V6 will be happy.
