Audio Transformer needed for Heathkit Marauder HX-10 Transmitter

[AK4UQ]

Need a replacement audio transformer for the CW code monitor circuit. The Heathkit part number is 51-3 and the schematic designation is T5. It is located directly behind the front panel microphone jack.

I'd look for an old tube type kitchen radio and take the audio transformer off it. No magic here.

Yup, one of the old AC/DC 5 tube radios from the 50-60's has a transformer that'll work fine. If you can't go that route then pop over to your local Radio Shack and pick up a small 120VAC to 6.3VAC transformer. It'll work fine as well.
