Not entirely because on most amps the AF amp heater is common to the output valves which may not like elevated heaters either.
There is also the hum problem to consider too.
On my submin triodes I found it essential to use DC heaters because hum levels on AC were so high.

for this reason I use a seperate winding on my toroids to feed the heater on the 12CT3 rectifier+series triode regulator / controlled warm up device used to feed a regulated screen supply, despite it theoretically having a H-K potential able to withstand 400V.
