The first picture in the previous post is my 845SE amplifier operating normally in a dark room. Yes they are bright. The second picture shows a pair of well used Chinese 6L6GC's being tested an about twice thair normal operating conditions. This picture is 4 years old and these tubes are still alive and cranking out the tunes. The third picture shows some rather toasted looking 6BQ6GA tubes being really stress tested in a Simple SE. I must report that they lived through this test, but I did manage to kill them later in another experiment.

The first picture in this post shows an 833A operating at 250 watts, well within its capabilities. The red glow is competely normal in this tube. The second picture shows a gassy 211 tube. The blue glow is NOT normal and it caused damage to my amp. The third picture shows the death ray shooting through the plate of a TV damper tube. The tube already had a hole burned through the plate when I found it, so I decided to finish it off while taking pictures.

Default A Little more mundane:

Haven't mastered the art of holding a camera completely still ( I know about tripods... too easy). 4 0D3 and 2x 12b4 on my preamp. Not a KT88 or such put neat glow none the less.

Waiting for my iron to finish my 300B and Simple SE. I'll have some photo's of those later.


Hopefully nothing in these will be blowing up soon ;-)
