Hi,
I disagree with the statement that tube preamps have a minimum gain of 20. My Line Stage has 10 dB of gain and some active preamps have only 6 to 8 db of gain.
9 pin tubes are the most common choice for preamps however 8 pin (octal) are excellent candidates as well. For example the 6SN7/12SN7. My preamp uses a 4 pin tube (DHT) 101D and it's superb IMO. It always boils down to implementation when all is said and done.
