Response is < + or – 2dB, 20Hz to 20kHz driving a 1.2 nf load. A 0.6 ohm resistor is used in series with the primary to quell a rising response which peaks at 25 kHz. (resonance). This resistor may be varied to adjust the response for different panel loads.

Note, the appearance may change from that illustrated, electrically the later transformers are the same but are “drop through” design, the 4 through holes are used to mount the transformer on a base plate.
