Re: Hallicrafters S27
Thank you for your helpful comments. I can now clearly understand why they used a 500 ohm line output impedance. Interesting to know that this is what came before the 100v line audio feed systems.
As for the 5000 ohm feed I guess is that most headphones of the day were higher impedance compared to what we have today.
Again many thanks for your help.
