This is the second generation Haut Brion. It uses two pairs of 6L6GA output tubes, one pair of 12BH7AEH, and one pair of 6AW8A. All of the tubes were replaced this year. Biasing was done this year by Arizon HIFi, Glen Bevel's shop who is the nicest person in the audio retail side of the business. I will include 2 sets of 4 matched 6L6GA tubes.
This is a great amp. Reason for selling is I have moved from the push pull design to the SET design.
Buyer pays shipping. I have all the original boxes. No returns. If you want to demo the unit first and pick it up in Houston just let me know.
