The only thing I've run across that needs some thought is directly heated tubes with indirectly heated drivers that are directly coupled. Some tubes are more sensitive than others, and some circuits are more risky than others. For example, a choke loaded driver with power taken from the output tube cathode/filament (the monkey-on-a-stick" topology) provides some protection from grid-cathode arcing.
