I have started to get the parts for this build.
I have a few question?
Where can I buy the power transformer for this? Also what is the part number? So I can order the right one.
Where do I buy the antenna coil from? Also the part number? So I can buy the right one.

Sorry it took so long for someone to answer your question.

Best to visit this link for a lot of discussion regarding parts: https://www.antiqueradios.com/forums/viewtopic.php?f=12&t=63526

To answer your question directly, you can use a F-82-61 toroid from CWS Bytemark with 35 turns of wire (see more at link above).

Transformer:

- Digikey # 262D6-ND ($35.43)
- Mouser # 546-262D6 ($33.12)
- Radio Daze # HX-262D6 ($31.42)

Thanks Macrohenry,

I was wondering if anyone was going to ask my question or not.
I did run up on the transformer.
Will look into the link and the F-82-61 toroid from CWS Bytemark.

Once again thanks a lot.

You would want the Hammond 262E6 power transformer. Yes, the F-82-61 torroid would be correct. Use 46" of #24 magnet wire, and wrap around 51-52 turns. For VC1, use an Arco PC464 variable compression trimmer capacitor. For the LED, use a NTE 3025. A Hammond 1591XXEBK enclosure would work nice.

Thanks for the reply. There still a few more parts I need to get Before starting this.
I'm guessing there will be more question when I do start this.
