RE: It's almost a crude crystal radio but the tuning portion is connected wrong....

You can protect this with a GDT - which are about $4 in qty 1 from Mouser.
These guys are mini versions of the OB2 OA2 glow regulators.... They conduct around 90V or so, so your FET needs to have a gate breakdown voltage above that....

Another longwire protection device is a simple neon lamp....
