Took off the metal tube retainers... don't really see the need for them.

Gotcha.. and that stopped the rattling altogether? For some reason I got the impression that the clips were there to keep the tubes from falling out. I wonder why they're even there in the first place if they're not necessary?

I wonder why they're even there in the first place if they're not necessary? I would think the Doc put them on there for a good reason, to keep them from falling out. If you move your amp around a lot after a while I'm sure they can wiggle/vibrate out of the socket. And some EL84's don't have the thickest of pins.

Well,
To answer the question of the wire retainers, I giged out w/ my Ghia last night... Lots of moving around, lots of cranking the amp, moving it around in the car.. back to the car. The tubes were fine. They were in the same place I left them when I put them in.
And yes, the Dampners really work. No rattle at all! 100% gone.

FYI the tube dampers I just bought 8 for 8.99 work great and you can still use the tube retainers. I put them on my Ghia and my Maz. My Ghia had some very rattly EL84s in it, so it went first. Cranked it up to about 1:00, nothing. Then 3:00, nothing. Then all the way up, there was some rattle but it was coming from V1, not the EL84's. I even tapped on all the tubes to be sure and sho nuff it was V1! I'm gonna have to get some more! Maybe even send some to the Doc to check out.

My tubes are now protected from any STD's (sonically transmitted distortion)

Just purchased and installed the dampers that Lefty suggested on ebay...These things are amazing...rattle gone... Turned my amp up louder than I normally play and no rattle whatsoever...what a great cheap upgrade. My questions now are ...Will they also make my tubes last longer? Lefty are you using one or two dampers on each power tube?

I noticed a little tube rattle w/ my new ghia too. I think I'll try a set - hell, they're only $15.00 shipped. Thanks Lefty!

I just bought a 2x10 Carmen Ghia, and it has a bad rattle that only resonates for certain notes and almost completely goes away if I press down on the EL84's. I haven't had time to swap the EL84's out yet, but I hope that fixes it.

I swapped them with the Sovteks that came in my Astroverb and the rattle disappeared, must've been a shipping thing.
P.S. These are Sovtek EL84's, not GT EL84S's like that came in the amp. Are there any huge differences?

dr z must already know about these things,, my rxes jr came with one each for the el84s and one for the ef86.. but, these are really simple o rings that can be purchased much cheaper locally at certain places,, but i cant remember where right now,, i have seen them they are "o"rings", usually black,, and this ebay guy,, two mullard 12au7's for buy it now over 200 bucks,, i bought three of them last year for 20 bucks each what a world.

Heatshrink, like Doc puts on the EF86's works great, and is cheap. I havent tried on the 84's but I suspect it would work fine. Anyone tried it on the power tubes?

ACK!!! The rattle is back! Maybe it was never totally gone, because I didn't really crank it or play it very long after replacing the tubes yesterday. I really can't tell if it's a tube rattle or loose screw or what... I'm thinking about taking it to Yarbrough's here in Memphis, but that's going to cost me $70/hour! All the screws seem to be tight on the bottom side of the chassis. I guess I could try to dampen the tubes with o-rings or heatshrink, but I don't know what else to do.

Ok, I've tried several different sets of tubes and the rattle is still there. I put the set of Sovteks back in my Soldano and there is no rattle, but it does have the heavy clamp that holds them down. I ordered a set of tube dampeners off eBay, so if those don't work I guess there is something ELSE loose in the amp. I've tightened everything I can tighten without taking the chassis out! This has kinda blemished my new Ghia owner experience

Have checked the rectifier to see if that is causing the problem?

The only tube I haven't swapped is the rectifier in V5 because I don't have another one to put in there. I'll order one today, but I'm hoping the tube dampeners will work as well for me as they have for others in this thread.

Both EL 84's and the 5Y3 rectifiers are really prone to rattle. The tube rings help, but some of the tubes just need to be replaced. Every EL 84 (other than NOS) i've used had it after a few hours of use (usually less thn 20 hours) and some were loud enough to be recorded, etc. and had to be replaced. I had it with an AC 30, Pro Junior, Astroverb, orange TIny Terror, Matchless Spitfire and with the Ghia too. Most times, I was the only one who noticed it...
The 5Y3's are prone also, I have had good success with the Bendix and the RCA NOS tubes, they seem to have a bit more substance to them, or you ca sub in a Weber copper cap. You can also sub in a bigger/rugged rectifier like a 5V3, but that will change the sound/feel of the amp a fair bit.
The tubes rings do help (I use them on all my EL 84's and EF 86's), but they won't fix a tube with really bad rattle in my experience.
