My part of the world components such as the venerable BB212, MPN3700, MV1662 are almost unheard of at the local stores; anyway I'm only getting started at attempting home-brew. Real VCO stuff will hopefully happen sometime in the future.
Basic theory tells me applying multiple capacitors in parallel adds up the effective capacitance a circuit will see.
Would I see the same behavior if several make-shift varicaps (say, 1N4007) were connected in parallel? i.e. does capacitance add up using varicaps in a tank that it does for any other capacitor?
