[Boatanchors] PS for tube stuff: Follow up

[Eugene Hertz]

Follow up question about power supplies for experimenting with tube gear...

I was looking through some tubes I had for possibly building a cw transmitter.  I had the following tubes that I had collected

one 813
two 211 (VT4C)
one 250th (it just looks so cool!) 

I then looked up some of the plate voltages/current of these and boy! Looks like I need a 2KV supply for the 211's for example (anyone have a simple push pull cw circuit that uses 211's?)

So I went to epay and did see some HV supplies, 2KV, 6KV 10KV etc.  So do you fine fellows use bench supplies that high to experiment with transmitter/amp circuits or is it just simpler to build an HV supply?

ONE LAST QUESTION!
Seems some tubes want DC filament voltages and some use AC? I would have thought that AC would induce a 60hz hum onto the signal, no? Can one use DC on a filament rated for AC? Pros? Cons? 

Ok, I lied, one last last question.  What is "getter"?!
thanks and 73
