[ARC5] Transistorized ARC-5 Receiver

[MICHAEL ST ANGELO]

Actually it is a good way to resurrect a gutted receive or a set missing tubes. Since you have to replace the capacitors you may explore the solid state option.

I am a longtime LF listener. In the 1970's I was looking for a battery powered receiver to listen to the LF band. I rebuilt a BC-453 with solid state devices.

I used JFETS's in the RF, oscillator and BFO stages and Dual Gate MOSFET's in the mixer and IF stages. I forgot what I used in the detector and audio stages. It was an excellent receiver with very low power consumption. I operated it form 12 volts.

I was going to built solid state converters for the ham bands but college, employment got in the way.

I referenced an article in QST or Ham Radio about a solid state conversion in a BC-348 for my design. If I find the article I will post the information.

JFETS are still available but it may be difficult to find Dual Gate MOSFETS. I believe some Dual GAte devices are available in SMT packages.

Happy New Year,
