it's 100w and I just retubed it with matching el34's...so, brand new preamp and power tubes. This head rules, but I just got a new Vox ac30c2 and don't need two amps. Cosmetically this thing is flawless. One knick in the tolex on the back and it's very small. Works perfectly and was by far the most versatile amp I've ever played. Great for Punk, hardcore, metal, grunge, noodley emo, whatever. Clean channel is perfect for just about anything too. It has had one owner prior to me, who was a close friend and case kept. No mods.
