Hi John,
I just wrap a few turns of hook up wire around the osc tube. Depending on the circuit you could use a capacitor to couple it but .1 is way too large, this could stop the oscillator from oscillating or dramatically shift it's frequency. The idea of loose coupling is to just couple a small amount of signal with out interfering with oscillator frequency. For capacitance coupling the counter I'd use something on the order of 5-20mmfd. Being kinda lazy I'll grab some wire and make a gimmick cap.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
