Tons of gain is what happens with tubes. Get the swing around 100v out of the second stage then step it down with a 5 to 1 output transformer 15k to 600 and you have 20v p to p, you decreased the noise by 5x and you have 5x the drive capability (lower output impedance) that will burn some of that gain off. I personally stay away from negative feedback as a gain reduction technique because I dont like the way circuits clip with NFB. and it messes with the gain control depending where you inject it.
