In an AM radio there are 4 types of IFT's viz Red, Yellow, Green, White/Black. could anyone tell or describe the details of these 455 khz oscillators like wire guage (swg or awg), number of turns in primary inclusive of tapping, number of turns in secondary and whether the secondary should be reverse mode or in line with the primary. these IFTs have a small core in which the winding is done and over it a ferrite core is fixed which is screwable for adjustments and these are all enclosed in a mettalic CAN. The primary winding is fitted with a capacitor valued at maybe be 180pf.
