The AES AE-25 Superamp, made by Cary, is a great sounding, versatile amp that can use EL34, KT88 and 6L6 tubes and is auto-biasing. It puts out 25 watts in ultralinear mode and 15 in triode. I own it and have also owned the Rogue Cronus. If you need the extra power of the Rogue it's a fine amp and it's easy to bias but I prefer the AE-25.
