That sounds like my Z-Lux did with rattly output tubes.
A couple of years ago I went through the same thing with output tube rattle. I bought a new set and had the same trouble. So I switched over to a quad of medium grade Tung Sol 5881 RI tubes, and no rattles, played it for quite a while with those. They're a little more 'Fender' like in tone, and a little more power. Then last summer I bought another quad of JJ6V6s for backup tubes for my Cure, and out of curiosity I put them in my Z-Lux. No rattles, they sounded great, and so I left them in and haven't had a problem since. Lots of happy hours on that amp and tube set.
Tube quality control is a big problem. It'll make you crazy (talking about myself here...)!
I think JJ has it together again as far as the 6V6, I sure hope so. Order a new quad and you should be good to go.

Tube quality really is very poor these days. No guarantee that a new set of tubes is a good set of tubes. I know Doc is continually searching for high quality manufacturers and does switch back and forth when he sees a trend in tube quality.

There are several threads about the rattling output tubes, use your search function. Here's one where Doc talks about 5881 tubes vs. 6V6 tubes: 5881 Tubes
I prefer the sound of the amp with 6V6 tubes. I have gotten good results with the last 8 JJ6V6 tubes I've purchased, so maybe they are doing better. Recently I've bought about 20 ECC83S tubes by JJ too, and lately they have all been fine. I usually buy from Tube Depot or The Tube Store.
I hope this information helps you. There's nothing like a Z-Lux that has good tubes in it. Like we've said, tubes are a gamble today, and now and then you get a bad one or two. But that's the price we pay for great tone, so buckle your seat belt and enjoy the ride!

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!

capofirstfret: I've experienced tube rattle in two different amps that I've had. In both cases I bought the rubber rings from Eurotubes and it fixed it for me.
