Re: Guy Atkin's Independent Testing of PL-380 7.5" Loopstick
Here's a website that has a photo of the radio in question. The Loewe 3NF tube was considered the world's first integrated circuit because they put resisters and capacitors inside the glass. The wooden framed one in front is the one he brought in. His coils were a pretty pale blue and seemed less dense. Maybe this one in the photo is for LW reception. It isn't very big. Almost would qualify for UL status. Later models were even battery powered, with a special version of the tube known as 3NFBs. What we won't do to avoid a little tax payments. You know that tube had to make that radio a lot more expensive than one that simply used three discrete stages. And one thing goes wrong and the entire set is done. The company did repair its tubes for you.toggle quoted message Show quoted text
I'd love to see how they wove that coil though.
I guess this is pretty far afield from UL, so I'll cease and desist. But coils and loops are so much of the fun with UL reception, even if it does move everything into the unlimited class.
