My current power tubes rattle in my combo amp. How are these Mullards in a combo Amp?

Combo amps are much more susceptible to tube rattle based on their close proximity to vibration and speaker movement. For this reason I couldn't say how these tubes would compare in terms of developing rattle. My suggestion for the least chance of tube rattle would be for JJ Brand tubes as based on feedback they are the least likely to develop this issue.

Can you do matched sextets of the Mullard EL34 reissue?

For a matched sextet of the Mullard EL34 tubes you would want to order a matched pair and a matched quad and indicate in your order notes that you would like to have all six tubes matched to the same specs.

Product Reviews
The tubes arrived quickly even though I selected free shipping when ordering. I inserted them in my Custom tube Matcher (see pictures). I adjusted the hottest tube (current-wise) for a bias current of 40mA at 425vdc with -39v on the grids. After 15 minutes of warmup the tube currents were 37.2, 37.3, 38.2, and 40mA indicating a close match of + or - 2mA of the mean value of 38.18mA.
I installed them in my Fisher X-1000 and adjusted the bias current for 38mA through each tube. My other equipment for this listening test include the new Classic JBL L100's, an Oppo UDP-205 Blue Ray DVD player, and MacBook Pro running the Audirvana App with classic Rock, Country, and Easy Listening WAV music.
My listening test revealed the sound to be very clean and well balanced from top to bottom of the frequency spectrum. I highly recommend the Apex matched Mullard reissue tubes.
I repaired a 2000 Marshall SLP 100 with a pair of these "Mullard" EL34's. The amp sounded fabulous and customer was delighted. Tubes had the Marshall sonic character.
However, these Mullard tubes are not Mullards. They are RFT's, formerly from East Germany. RFT manufactured tubes branded as Siemens, Telefunken, and ITT Lorenz. RFT machinery/tooling was acquired by the Xpol-pul (Reflektor) factory in Russia. Xpo-pul EL34 tubes are now branded by New Sensor (Mike Matthews).
The stapled plates, larger rectangular plate slots, and, especially, the dimple glass top of these "Mullards" point directly to RFT manufacturing. I have original RFT (Lorenz) tubes in my '84 2203 MV. The tubes are as close to a "real" Mullard as you can get. And, they look exactly like a "Russian Mullard."
Got this for my Hiwatt Custom Little D. It needs time but It sounded great from the first day.
These Russian made tubes are a great match for my sovtek mig-60 head. Really gives it a good platform for its original sound. Don't waste your time with sovtek EL34's. These Mullard EL34's should do the trick ;)
These made a huge improvement over the jj EL34L tubes that were in my Marshall DSL.
Very expressive sound in my Seymour Duncan Convertible 100.
The Mullard EL-34 set really brought my Marshall DSL-40C to life! Glad I bought them! will buy more! Highly recommended!
Awesome! I'm glad I got the Apex matching this time- I matched the negative bias voltage on all 8 and their plate current matched exactly. They also cancel even order distortion products almost completely (as they should in a perfectly-matched push-pull amp).
Mud Machine. I guess if you play rock and blues, this tube is ok, but I play clean blues/jazz/R&B, and this tube is absolutely terrible for that. Low mids are muddy as hell.
BTW: I tried them in my Matchless Clubman, which is a great, clean amp (without the mullards)
Its been about 10 years since I first tried these "Mullard" EL34's and I am even more impressed with them now than I was then.I was more skeptical then of their quality and durability. Now I can say that I have used two pairs of these in my 1987x reissue in 10 years and both pairs are still good and strong. Im about to install a new pair..thats actually what im doing here today. New Sensor makes a few tubes that are just dead on and this EL34 mallard is one of them
