@vicweast I should have been more specific. The integrated is really a hybrid. Tubes in front of Class AB … versus all tube design. The tubes I rolled are small input tubes, unlike your power valves. At any rate, I replaced the stock Chinese 6N1’s with a matched quad of 1960’s Amperex Orange Globe 6DJ8’s. I prefer the sound of these more than anything in that class - except maybe Amperex PQ (6922).
The unit was purchased direct from China via eBay. One last thing: Lots of folks like to trash Chinese gear, but I found this unit to be fairly well-built and definitely up to “second system” task. To that end, it sounds great to me and that’s really all that counts. The only annoyance was it gave off kind of a funny electrical smell when it was new. It took a little time, but that finally disappeared after it was broken in
