Purple Glow

ANDYLASER · 24th April 2009, 12:00 PM

I seem to remember a thread about valves which emitted a rather nice purple glow when operating. Does anyone know which one this is, or more importantly what amp it was referring to and is it any good?

Thanks.

You probably mean American / European voltage regulator tubes...

0C3 is the same shade of purple/pink as 0D3. 0B3 is an absolutely beautiful indigo, but it isn't so bright...0A3 is of course orange( and quite bright ).
cheers,

Some Xenon filled rectifiers also glow purple.

Did that picture come from the "Most Dangerous Lash-Ups" thread?

I had an old Ampeg Bass amp with an 80 rectifier that not only glowed purple, but pulsed with the music....prehistoric lightshow !!!!

Why? What's it do? Didn't all the Hickok testers operate the 83s in that position?
