6p21s Russian direct heated tetrode is really good. Very neutral and low distortion - lower than 4P1L and 26! See the 4P1L dHT line stage thread for details...

I want to have plenty of headroom for my trafo. Unfortunately 300V trafo only available in 200VA. I was thinking of 400VA since I will be using dual sshv2 regs at 45ma. They only come in 320V secondary. Is this too much or will it be OK?

100VA will be plenty for your purposes.

That looks really fresh! Sorry SaladThe Antek I am looking at that is 200 VA, has dual secondaries of 300V/.30A and 6.3/4A. If running dual 45ma regulators, isn't that awful tight.
