gk mb800 issue

[camdoug1990]

Wanting some help on my mb800. At a gig on Tuesday it started limiting on only 1/4 volume then just stopped working Completely. Now the lights on the front have all gone very dim and are flashing.
Can't get any sound out of it at all. Just wanting to know what this issue could be?

The first port of call is probably to ask for advice from the UK distributor - Polar Audio:

Did you buy it new? Because the distributor will most likely refer you back to the retailer

Spoke to gk and polar. They said I had to contact gak where I bought it, stain waiting to hear back from them. But gk gave me a diagnosis at least ....
"Their might be an issue with the voltage (+ or – 15V), either from the Preamp (resistors might be open) or from the power amp."
