Manley Chinook question

I bought a used Chinook here on Audiogon. I had for about a year and it started to hum pretty loud. I called Manley and they were fantastic on the phone. I actually boxed up the Chinook and took it to The SHOW in Irvine where they had a booth. They allowed me to drop it off and they took it back to their shop. They totally upgraded it and within 2 weeks they shipped it back to me.  Cost for everything:  NOTHING!  That was a year ago and it is perfect.  They are a fantastic company in my experience.

My Chinook's serial number is 011 so it was literally the eleventh unit produced...about 5 years ago I believe...and they knew I bought it used. 

I rolled the tubes once but put back the originals soon after. The stock tubes were much better. 

My mistake then...that is excellent service. In the past I'd heard they weren't too kind towards servicing 2nd hand gear. The Chinook looks like a great stage.

Thanks for the info. I might just get a used Chinook. If I don't like it I will
sell it and not lose too much.

My understanding is the Chinook is warranted for 5 years to any owner as long as the original owner sent in the warranty card when it was new, so if buying used get the serial number and call them to ensure it is still under some warranty?  I think they were released about 5 years ago now so some of the early units, like mine, may be nearing the end of warranty. 

I bought the Chinook special edition with the NOS tubes and ended up replacing them with the stock tubes. IMHO the stock tubes are better at least in my system.

Manley customer service is second to none.
