Hi folks, anyone have a similar experience with the problem described below?
I've an Ashdown ABM Evo II 500 amp that is intermittently cutting out every so often. There is still input signal from the bass just no output and usually a simple off/on reboot will solve the problem (although not always). I'm running it through an Ashdown 410t and TE 1518c cab, both input/output dials usually sit between 10/12 o'clock) - have checked all leads, bass battery (mute button) etc and they are all fine. Straight of after reading some other users Ashdown problems that it was the effects loop either connections or pcb but that board seems to be working fine when I hooked up a pedal through it. I opened up the amp, all connections/wires/fans/solder joins etc seem fine. The cutting out seems to happen when I press the flat/shape button while amp is on (but not all the time) and I also noticed recently that if it does cut out cranking the input dial up to full seems to get everything going again.
I've emailed ashdown who basically said you need to get this checked out (duh). Being based in Belfast shipping the thing over to Ashdown and back again is going to be costly so was wondering if anyone here has had the same problem or has an idea of what the problem could be so I can either repair it myself or drop it in to a repair shop here with a specific-ish diagnosis (because as I say the problem is intermittent so the amp could seem fine to techs over here).
Any help would be appreciated.
