There's an old ham radio trick for making small coupling capacitors just
by twisting two insulated wires together.  The resulting capacitance
depends on the insulation and length of the wires.  They're called
"gimmicks".  I needed to make a 2 pF antenna coupling capacitor for a
garage door opener receiver (tube-powered, so it's OK) a while ago.  I
snipped off about an inch of zip-cord and put it in the circuit.  Worked
great.
