Hi all
FWIW the 'correct' startup sequence (at least on mine) is:
1. Red HB light & 'Protect' light for about 30 seconds
2. A gently audible mechanical 'click' then a switch to green HB light and 'Ready' light.
I wonder if the LED has failed on @RikiB's?
I don't think having the amp on a cab will be a contributing factor to any problems..!
Also, I am fairly sure Lezsek is way on holiday at the moment, so if you're getting zero / brief responses, that might be why.
