Hi, I have a Creek Destiny Amplifier which was working fine, but now a couple of minutes after powering up there's a relay switching sound and the speaker protection steps in, the speaker channel (A/B) and input selector LED's turn red and the amp becomes completely unresponsive leaving only the power button active.
I initially though there was an issue with my speakers, but swapping to various speaker and cables made no difference at all.
The amp doesn't even need to have any speakers/cables/source connected or selected to enter protection mode.
The Destiny does have some history, and has been back to Creek for 'refurbishment' by Mike himself - there's a sticker on the main board saying so. Just by removing the lid It's pretty obvious one channels entire pre & power has been completely replaced. After searching many forums in hope of a diagnostic test procedure, nothing came up other than one guy who had exactly the same issue as me, and although his amplifier was inside the warranty term, he had an incredibly difficult time with Creek to get the amp repaired, received the amp back after quite a considerable cost to himself and sold it on to recover the cost.
My amp was purchased pre-owned and advertised as 'refurbished' by Mike Creek himself. I do wonder if my amp is the actual amp that the above guy had many problems with? Regardless, I contacted Creek and I was advised they are still able to service the Destiny, and they seemed aware of the serial number, to which they hinted it may not be cost effective to repair the Destiny compared to replacing the amplifier.
The amplifier works fine and sounds great up until the speaker protection steps in, and I really would like to get this amp up and running again.
There is no DC present on the output and the bias seems fine on both channels, the rail voltages and transistors seem in tolerance from what little info I can find. The output relays don't seem to be sticking. I have no idea what the fault is, I can only presume its the speaker protection itself causing the issue. I don't have access to a scope or the knowledge how to use one, so it's pretty basic measurement testing.
Questions: has anyone had any issues with a Destiny before? Do Creek have any kind of diagnostic code finder? I don't have access to a circuit diagram - Is there a dummys guide present anywhere for fault finding speaker protection problems and output stages please?
Thanks,
Ant
