The Blackstar-HT LED of Post#1 appears to me amber, perhaps orange...
Anyways, they did at least try to match a reasonable cathode color.
Might be one of them twin triodes where filaments are entirely hidden?
I need to pop open topside and see which dim bulb actually got abused?

3PCBs make it hard to get at the triode from underneath.

Good guh-reeeef!!

That won't offer the user any, uh, "protection", BTW. 😉

And I thought I was gonna be the most outrageous guy here when I suggested 22" rims and 20-series tires. What's next, thigh-high leather boots and mascara? 😀
