I had an original 3B, was the original owner since 1982 or so. I had it fixed once when it was about 18 years old, was blowing fuses in one channel. Bryston fixed and brought up to spec free under warranty, though I had to pay shipping one way.
Same 3B had a channel die last year. I called Bryston, and they still service the unit (probably same generation as the 7B). However, they wanted $500 flat fee to fix it, and they sell used/serviced for around $700 - $800. So I decided to sell it as is and got $350 for it which I considered a win.
Keep in mind, if you don't have the original factory packaging, you need to buy if from Bryston. They won't accept anything not packaged with their packaging.
One repair 38 years says they're reliable. The only question is how were the 7B's treated by the previous owners.
