Yes it is a famous mistake, it was first discussed here when found on a 90.
Indeed how does power a tube's plate connecting it to the GND via a cap  . The absnse of B+ filtering notwithstanding. They have it across multiple radios. One tie dot. Many confused people going nuts troubleshooting.
Though this only occured when rewiring, otherwise the wiring would be in place.
