Hey guys,
I drafted this schematic a week or so ago. Please tell me what you think and if any improvements could be made. I will not be implementing any global feedback just yet. Here's my schematic:

One thing to note: the maximum plate voltage is 400V for an 807. I have seen several circuits that push this rating. The others I've seen also use lower resistance cathode resistors, but I am hoping by using a larger value, I will prolong the life of the tubes. Here's the curve:

Thanks!
