I am using Linlai 6SN7 in my Supratek Cabernet preamp. I have noticed that the tubes run vey cool to touch even after four hours of use. Is that normal for these tubes? Thanks.
invalid. All my tubes run very hot except for Linlai. Could the tubes be an issue? They sound really good though. If anyone running these tubes in Supratek can check and let me know that would be great.
atmasphere. Good to hear that. I saw a video from Kevin at Upscale Audio that if tubes run cool then one needs to worry. Naturally I needed to confirm that. I do not know why if tubes run cold we should worry.
