Wouldn`t say so. Only few ppl have them here with Aune T1 and someone had poor distorted sound with his NOS 6N1P tube.
6N23P / 6N27P are drawing around 310-330mA current and and all those different tube types I have are around that. Tube with highest current I have is ECC189 which is around 365mA. Also ECC88 seems to be 365mA actually. Would be interesting to get answer from superlux about how much mA Aune T1 can handle.
Just heads up, wouldn`t be sure about those noticeable higher currents because it might work ok but it puts higher drain on Aune T1 and might eventually kill some internal components. But so far I haven`t had any problems with my ECC189 and ECC85 is by numbers only ~70mA higher though, it might be just the "limit" for Aune.
Who knows, just be warned. I won`t add this tube type to my tube list yet because we need more information.
Also about Mullard ECC85 sounding better than Amperex 7308 - it`s totally subjective and may not be the case with everybody.
I think you missed the point. The original tube offered in the Aune was a Chinese 6N1P, which has a current draw of 600ma on the heater circuit. If you want to compare specs, the ECC85 is actually closer to the Chinese 6N1P than the 6922 is.
Long story short, the ECC85 draws LESS current than the tube these came with at first.....the Chinese 6N1P. The ECC85 is not going to hurt a thing.
And I agree about the sound....everyones ears.....taste.....and needs are different. To me, on my setup, it sounds better. Hows that?
