Want to convert TV audio to headphone or speaker. What impedance transformer ratio is reasonable ?
Present speaker is 14 ohm. I tried a 1000 ohm to 16 ohm, it cut output to speaker by 75%. Thinking I need 1:1 transformer and probably impedance is not critical as long as it is 50 ohms or less. I will be switching between earphones or speaker. No fidelity requirements.
