I can't believe there is no thread for Woo Audio in this forum, save for the acknowledgment that Jack communicates well.
I had to put him in the middle of a difficult situation recently when my second-hand WA22 arrived poorly packed and damaged in transit, although the seller wasn't directly at fault. At the same time, Jack had both the seller and myself in an awkward position. Not only did he repair the amp, but he performed a requested modification and did it all perfectly, in record time, and was quite courteous.
As I did not purchase the amp from him, he could have charged me whatever he wanted for the repairs and return shipping, or even worse refused to deal with it at all. What he did is perform the repairs and upgrade for a very reasonable price, and gave me a proper shipping carton, free, that resulted in about a 40% discount for the return shipping.
What I Grokked from this experience is that Jack really cares about the products he sells, and the people that use them. He also cares about what should always be the most important part of customer service, the building of a long-term relationship.
I have also read repeatedly in the Woo amp threads that he is quite a fountain of knowledge regarding tube-rolling possibilities with his amps, and always provides the correct answer upon request. I have not used him for this service yet, but am looking forward to.
I highly recommend Jack at Woo Audio and their products without reservation
