my GU48 does....
Hi Eugeny,
funny....at those voltage (some more current) my GU48 does show some reddish colour.
I noticed your wire-size of the filaments: maybe i'm mistaken but those look incredible small. It's 10V/10A were talking here.
If your wire gets warm....you know you are firing up your GU48 not at the intended 10V/10A....but less.....
In what kind of amp you're going to use this triode ?
The GU48 is a real bass-monster, but not as detailed in the heighs as American or Chinese 833's. But for the price....who complains ?
Lots of building pleasure,
Reinout
