Hamradio - Blog Posts

Project finished. Using 2 6SN7GT tubes. It can use plug-in coils from the original Knight Radio kit. (Thanks to a socket found at a recent hamfest)

3 tube (41, 42 & 25) regenerative built inside a case I found at Walgreens. Coils for multi bands. Works great, quite sensitive, but the vents aren't cutting it. Going to need a cooling fan.  Listening to BBC at the moment.

I got bored and went digging through the box of tubes again... Found a nice looking 6F6 GT and a 6Y6 GT, and kind of ran off in high spirits and decided a little broadcast band receiver would be a fun project. For this project I wanted them outside the box (CD case) where I could see 'em. Mounted all the heavy components. (back-to-back Radio Shack 12V CT transformers to make what amounts to an isolation transformer, picking off filament power between the two... Audio output transformer...) I haven't even decided if it's going to be a regenerative or something that requires less fussing with during operation. Any suggestions, anyone?
