as suspected, just received another fail response from a repair centre, despite making it clear that it needed service on the software side........
............"Sorry your unit is no longer repairable due to age. No one will be able to get any parts to repair your unit Thank you"
this is actually not that surprising to me, one of my own local guys who is an amp wizard froze when he saw the unit, combination of the digital and topology aspects I suspect
what's interesting is that they continually refer to this unit as old, lol
had similar issues on the past with a software issue on a Hegel amp where in the dealer ended up just sending me a new unit after months of failed warranty/repair attempts
