There is lot of information about early SSB and DSB operations in the GE Sideband Handbook (1961). Lighthouse Larry is very informative. Early in the book there is a guide to help homebrewers select intermediate frequencies that will work well in SSB and DSB rigs.
Here is the book. Remember, we are dealing with tubes and high voltage here: one hand behind your back. Volts jolt but mills kill!
