Hello,
My daughter is taking an engineering class in college and for a class project the students have to each build something electrically/electronic from scratch so I am going to help her build an early 20's style 2 tube radio.
My question is, I want to use a crosley model 51 schematic but the 51 coils are loose coupled that move closer/farther to each other for tuning but the only coil assembly I have is a variocoupled coil (at least i think thats what its called) the primary coil mounts at a 45 degree angle and the secondary turns 180 inside it.
Would this coil work to tune the circuit being that the variable capacitor in the 51 circuit tunes the antenna rather than the primary coil, like in a 1 tube regen.
Thanks, Todd
