BTW Rob, whereabouts in Australia are you?
Hi Mellowtone,
Randwick, Sydney.
Nice amp Jeb! Is that another DIY amp? If it is, I'm curious about the front panel lettering.....
Thanks! Yes, it is a DIY based on 6as7g. The etching on the faceplate is derived from my last name (DePaiva). People referred to us as the DP's back in the day. The faceplate was too plain beforehand.

Is the control/volume lettering dry transfer with clear coat, silkscreen, etc? I see that your logo is etched.....

It's etched with black color fill. I had front panel express do it.

What are the tubes Piero7 is lighting up?
It is a Russian GU29 and like my 211 it is not supposed to do that. It is a gassy tube. Details in this thread.

And what the heck is an Eimac 450th?
Eimac makes big transmitting tubes for radio and TV stations, ham radio and short wave broadcasting. The 450th is one of their small ones. Several adventuresome DIYers have become bored with common audio tubes and have employed some of the smaller transmitting tubes in audio applications. Most transmitting tubes are not well suited for audio, but some work very well. The 211, 845 and 833A tubes shown in my glowing post are also transmitting tubes.
I use SED EL34 for my Dynaco amp as well. That picture must have been taken soon after turning it on. Mine does that too but the blue glow disappears a few minutes later.The internal glowing of some SED EL34s in the Dynakit VTA-70
How do those mesh sound compared to other 300B?Bizarre blue glow from a pair of Shuguang 300-** in a Tubelab SE

Far too much blue in those ElectoHarmonix 88's: Apart from camera over-exposure: What's the cause of this type of blueness ??
Not sure. Found that picture during a Google search and it got me interested in tube glow.
