I have a chinook and it’s been trouble free. Your issue sounds like bad tubes to me. Maybe it’s overloading with incorrect settings? But you switched tubes and the distortion switched too. That’s a sure sign of a bad tube. Contact Kevin or buy some new tubes I say.
Manley Chinook - chronic issues
I’ve had this Chinook that I purchased from Upscale in September, it has no time on it. I have not enjoyed a single record at this point. I have been plagued by chronic static and popping issues. It is defiantly the Chinook as I have used other sources and a different preamp with no issues. There seems to be a constant crackle pop on all vinyl and now to add insult to injury the Chinook made 4 loud bangs back to back tonight and it really worried me so I shut down the system. These were not dirty vinyl click or pops but loud bangs.
I had narrowed down that one of the tubes on the output channel was bad, and it was replaced. Yet the issues continue and now have progressed with the loud bang. I also have a loud "fuzz" noise coming through the right channel. At this point I swapped the left input channel to the right and the "fuzz" noise flipped to the left channel. More bad tubes?
I can’t deal with this preamp anymore, what was suppose to be a get away has turned into nothing but constant stress.
Bad tubes? Bad board?
