If you're wanting to use 2A3 because it's DHT I suggest looking at 4P1L in triode connection.

There's a lot of nay-saying on this thread, but the 6A3/6B4G is well suited for preamp use. Using a 5-10K attenuator at the output will maximize SNR and reduce the issue of microphonics.

Hmm KT88 preamp you say... Tell me more
Is an EL34 preamp close enough?

Not trying to be a wiseguy here, but there's nothing really new under the sun.
