These amps are rated 8, but will pass for 9. They function perfect. I am second owner. I have put a complete set of new tubes in them for shipping and will also send another complete set (28 tubes) of used tubes with the amps. They will give the buyer years of enjoyment without worry. They will be packed in all original (perfect condition) boxes. If your looking for awesome sounding high power tube amps, that drive difficult loads, here you go. I have steady positive feedback going back 15 years here. Buyer covers paypal and shipping. Shipping will be four boxes. 2-amps and 2-tubes. Local pickup in N. Virginia would be great too.
