Grant Fidelity responded to my email promptly! I just emailed them this week on Monday 3/14, asking if Linlai was going to start producing KT88/6550/EL34. I received a response from Grant Fidelity (Rachael) the next day in regards to my question informing me that Linlai was currently working on a KT88 for production that would hopefully be available soon. I was very excited to hear this!!!
I have purchased tubes from upscale Audio in the past, and I have been very happy with both their service and tubes. What I took from the video was that he was just warning his customers to not get taken advantage of, and be patient which I think is excellent advice!
