Even the best of us have made silly mistakes and as you rightly point out, others will be reading this.
For the low HT current needed by a radio you could just use a half wave rectifier on the variac output and have the chassis conencted to neutral. Not sure what sort of derating factor I'd apply to a variac for using it with a half wave rectifier but at least x5. So a 2A variac will be more than adequate.
