I have a feel good story....

Right on.... having worked on complex state of the art electronics ( including traveling wave tubes) most of my career...all the engineering into rated MTBF on components, N+1 redundancy, quality circle culture... things still fail... I get that, how it is resolved creates or kills customer trust forever... 

Both Manley and Upscale did a 4/0 job this weekend...AND on top of that the Stingray really sounds great.. 

OP, Where did you travel with your wave tubes?

LOL... APD Site 2, China Lake, Hulbert, Rucker, Huachuca, Minot, Beale, Loring, Kadena, Wakkanai, U’Tapao, Moshav Zarit, Haifa, Fulda Gap, Lakenheath and Alconbury... there were other spots but my memory fades now..

Since this is too perfect to pass up, I will add my experiences with Manley Labs Customer service. It is not at all a big deal in comparison to the OP’s experience and that is exactly my point. I wasn't buying a muilti-thousand dollar product. I have been buying stereo pairs of RCA jacks from Manley Labs for years. They are by a very good stretch better than just about any other brand used in new audio equipment. I found them on eBay and have never switched back. I wonder just how many of these RCA jacks I have bought to make my products, rebuild other peoples old units, etc. Every single time, Manley Labs, yes, up to and including Evanna herself, make the effort for my multiple orders 100% correct. If it didn’t happen, I was immediately compensated, or a new batch was sent out.

I only wish they sold all the other components that I need!
