[Amps] how to estimate the Q of a tank circuit

[Johan]

I constructed a RF deck with a Pi-L tankcircuit. Using a network analyser and
a small Rl resister on the tube, I've obtained a good match to a 1.8kohm Rl value (better than 60dB returnloss). But now I'm wondering if the coil used has a large enough wire diameter to handle the current hence my question on estimating the Q of the coil. Most seem to suggest a low 10-12 Q to be used in a tankcircuit.

Anyone out there that can help me?
