@bdp24 Roger and I disagreed about his assessment of the 6SN7. For some reason he only used the early Tung-Sol documentation to support his views of the tube as you can see in the YT video. The issue was corrected by Tung Sol in later versions and by different manufacturers.
I agree with his assessment of some of the 'boutique' fuses. If they have a Teflon tube inside, the fuse will not blow correctly and so can damage the equipment its meant to protect!
