I'm looking for ARRL radio communication books issues 1960s, 1970s & 1980s. I need to get some information about some basic radio circuits without ICs.

For IF circuits, this is all I can find:
"When two or more stages are used the high gain may tend to cause instability and oscillation, so that good shielding, bypassing and careful circuit arrangement to prevent stray coupling between input and output circuits are necessary.
When vacuum tubes are used, the plate and grid leads should be well separated. With tubes it is advisable to mount the screen bypass capacitor directly on the bottom of the socket, crosswise between the plate and grid pins, to provide additional shielding. As a further precaution against capacitive coupling, the grid and plate leads should be "dressed " close to the chassis.
