Do poweramp tubes glow the same brightness???

[strumminsix]

Looking at my LSC from the back I notice the 2 on the left (by the rect tube) were much brighter than those on the right. I read and know that the tubes are paired outer inner so I didn't think one was bad.

This was after 30 mins of playing at "ya I'm home alone" volume.

Any thoughts?

the power tubes further away from the recto tube should be brighter, as they are used more and use more power....wel actually i think its the 1st and 4th one that does cuz there in pairs, all i know is that yes some of them will be brighter but should be 1st and 4th

With diode rectification, the 2 closest to the recto tube were brightest, the next one was dim, then the one after that moderately bright

Said differntly:
recto - bright - bright - dim - moderately bright

there is no problem with tubes with different brightness, don´t be afraid
