What is this? (pilot lamp fading on Roadking)

[samuel_js]

Hi all from Sweden,
As you know (roadking owners) there's three little lamps on the left side of the head called 5U4 - DIODES - 5U4. Well, my second 5U4 is loosing it's power. It was very bright but know it's almost dead. What does it means? Is it the tubes? Is it just the the lamp? In that case, where do I find a new one and how do I change it?
Hope you can help me with this one.

Thank's a lot
Samuel

That's your rectifier tube pilot. It's only on when using full power. You could probably get a replacement from Mesa if it's bad.

Hi, thank you for the reply. It's nice to hear that's nothing more than the pilot... I e-mailed Mesa Sweden yesterday. Well see what they say...
Than you.
