Excellent condition. Tube Complement: (4) EH 6550 power tubes; (2) 12AX7A/ECC83 pre-amplifier; (2) 12AT7/ECC81 power drivers. In addition will add (4) Tungsol KT 150 tubes for tube rolling the 6550s. It can also run EL34's, but will produce lower wattage. The KT150's have better bass than the 6550's. Very easy to bias, I prefer the 6550's, absolutely beautiful sound. You will be getting over $500.00 worth of tubes. I have it hooked up to Theater Electro Voice dual 15" woofers with horns and it drives them effortlessly and sounds magnificent. Come and audition them. I am downsizing my collection down to one system, due to old age/health. To be honest, I just put the 6550 tubes back in and set the bias and I was floored by how good it sounds. I'm very tempted to keep it, but I am hanging onto an older AR D90 with double the number of 6550s. This is an incredible bargain and since I'm downsizing and already sold a huge amount of gear, not interested in trading, or bargaining. If you are interested come listen to it, but this is the price. I will not even respond to lower offers period, I will just keep it. 
This came from the factory with 6550 tubes. No factory box. you get the cord and user manual. This thing is 55 pounds and built like a tank.
