Not a dumb question, because this particular set does not use a 3.58MHz crystal controlled oscillator like pretty much everything else. It's a bit more like a horizontal sweep oscillator AFC circuit controlling a reactance tube based off of the color burst and it actually has a control labeled "color hold". Guess that's why the alignment instructions call for an external crystal oscillator.
