Sorry Vic, I misunderstood what tubes were failing. Thought the Ayon tubes were re-labelled Gold Lions. I agree with jond's guess about the identity of the Ayon stock "Treasure" tubes. Given the stock tubes are something other than Gold Lion, I'd definitely be pulling them and plugging in those Gold Lions. If they run OK then you will know it's bad tube quality and not the amp. By the way, looking up the Ayon amp on-line I see bias is listed as both automatic AND manual. Not sure how that works but if you are able, check the bias. A check and adjustment of bias is always recommended prior to installing new tubes. Apologies if this is something you already know. Good luck getting things sorted out.
AYON KT-SX Tube quality (failure rate?)
I bought a new/demo ("was only played at CES this Jan 2016...") AYON TRITON III from the US distributer this January.
Within 3 weeks 2 of the 8 KT88-SX tubes either expired or the amp complained about the tube. The vendor said: "90 days on new tubes..." ...which meant I was out of luck given his logic. New tubes cost around $180 or so.
I have either spoken with other Ayon owners on this or other forums, in private (after posting about Ayon) or when seeking to buy these tubes from them.
Guess what?
They have had the same failure rate.
Please weigh in: I am relatively new (1 year) to tube gear and have no idea if I should expect more monthly replacements. (I bought 3 matched quads of new Gold Lion KT88s, but the Ayons sound quite good to me, I just am appalled at the failure rates I experienced or heard about.)
