The front end was engineer designed to work with a broad range of tubes. No optimising intended or required. This is a tube rollers dream amp. The front end originally designed for 6N1P. I replaced it with a universal (4SU) frontend. My other EL34/6L6/KT88 amps all use 12AT7s not by design but by choice. Great tube in my 6L6 amps but here the upmarket Tung-Sol gets a place. Also I have Lin Lai 12AU7s to drop in. Universal design allows me to do this without fuss.
