KEL84 Bi-coloured LED

[Mark]

Hi,

I took the bottom off my KEL84 recently for the first time in 12 years to try a stepped attenuator. At the same time I thought I would sort out the bi-colour LED which has always irritated me by starting green and going to orange. Being a simple soul I thought simply swapping the wires over might change it round to start orange and then go to green - which is more logical. Well the attenuator is fine, the amp behaves normally, but the LED now starts red and then goes orange ? How do you get red from a green and orange LED ?! Clearly it's not as simple as I thought. Any ideas anyone ?

Thanks

Mark
