Default Fake glow LED under valve in commercial devices

Blackstar Drive-HT.

Looks simple enough on the outside, but inside:
Extremely complicated, 3 PCBs crammed in there.
Only thing I'm claiming "fake" about it is the glow.
Clearly they didn't trust ECC83 filament to provide
the required lightshow.

One word

“marketability”

Cruise lights for tube amps.

I've noticed a couple Chinese amps with high intensity blue LEDs mounted in the tube socket. They're clearing aiming at a young-ish and dumb-ish marketing demographic (which I believe is a huge one.)

I saw some amps including a McIntosh preamp that had LED's under the tubes, I don't like it at all, it takes away from the warm glow of the filaments

Well, in some cases the LEDs might be actually serving as part of bias or CCS circuit, so it's not necessarily always about "marketing"

Wait until you see the next one. It will make the RLD seem... understated.

The LED's could be located under the chassis. If they're positioned under the tubes to give them a nice blue glow, it's all about marketing.
