RE: What are the pros and cons? nt

I have used paralleled 6SN7s in SE 2A3 and 300B amps. The other thing, I usually load them with a CCS and LED bias them. Good power supply isolation on top and full mu combined with no cap bypass on the cathode. Heresy for some but the results sound good and you run the tube with a horizontal load line. I use two red LEDs for about -3.5V bias.
With the CCS, a 6SN7 has enough gain for a two stage amp if you use a preamp. If you're using a passive or straight out of a DAC, you should look at the voltage gain available.
