Re: Hallicrafters S27
I found a manual for the S-36 receiver which also has a 6V6 push pull output stage.
It has a different arrangement for the headphone output.
In addition to the 500 and 5,000 Ohm grounded windings which are used for an external loudspeaker such as the Hallicrafters PM-23, it has a 600 Ohm balanced to ground winding for headphone and balanced line output.
Both windings are rated at 3 watt. It recommends using a 5 Watt speaker.
The Hallicrafters PM-23 speaker incorporates a 5k Ohm step down transformer for the voice coil.
