Hi
Simul c+, loaded with 4 sylvania 415.
All tubes ran with the normal yellow glow and sounded out of this worl, but when i put it in class A mode the two outer tubes began to glow blue, but after i swiched i back to simul the two puter tubes now continued glowing blue, and the two in the middel now had a faint blue colure in the middel of the tube.
the even more strange thing is that after i turn it off about 6 sec later in makes a funny beeeehhhw sound in a fading sound.
Then i tried putting the outer tubes that where glowing blue in the middel and the two that where in the middel before to the outer sockets, now the blue glow is gone and it dossent make the funny sound when i tune it off.
But the sound also seem to have lost a littel of te mojo and volume, is this a perfect case of the outer tubes going bad ?
