“Do you have any videos/clips of the V3 pre and/or post retube?”
–Unfortunately I don’t have post-re-tube… but I would be glad to slap some recordings together for you so you can hear what the V3 sounds like with the integrated quad of E34L’s and 6L6′s sound like. I DO have a clip of the amp when I first got it (stock tubes, about 2 months old):

My tone is the one thats much more obvious in the mix. Give me a day or two and I’ll get a video up of the amp as it is now.

“I’ve owned a V3 since they released but I’ve never really liked the sound for the style I play (death metal/grindcore) as much as I wished when I decided on ordering it; still this amp is awesome for the price.”
–This is a fantastic amp and can certainly do what you are asking it to. The answer is in fact, getting the right set of tubes.

“For my tone the amp seems shaky or not as stable or solid with the sound and sometimes fuzzy imo. It doesn’t reach the low end like I want I need a thicker lower sound. I’m running effects now and I’ve got it a lot better which is why I have yet to retube it however I’ve contemplated retubing it for 4 years now. “
–After 4 years there is a very good chance your tubes are just on their way out, hence the fuzzy sound and lack of low end definition. Tubes don’t last forever and need to be replaced every so often. The more you use them, the quicker they will die out. This is exactly what my V3 started to do.

“For the first year+ I remember reading a lot of negative things about retubing and receiving a “helicopter” or “motor boat” sound. In addition a lot of online resources mentioned the original V3′s weren’t assembled to quality so to speak. This makes me nervous about retubing being a 1st Gen V3 owner.”
–I am also a 1st Gen V3 owner. The ‘motor boat’ sound tends to happen in CERTAIN V3′s when run up to bias (meaning the tubes are being driven hard enough to sound their best) in EL34 type tubes only. This includes the KT77. Unfortunately, the only way to find out is to re-tube it and see what happens. MY amp does this. It’s annoying, as I wanted to run KT77′s and they just don’t have the same punch when biased too cold. When run in an integrated quad, the amp won’t motorboat, even with EL34′s. Once again, this doesn’t happen with 6L6 type tubes. I don’t really know why it does this. The newer generations seem to address the problem, but I have yet to try one. This problem aside, I assure you they are very solid amps.

You can get that low end you are looking for with KT77′s… they would be perfect but you run the risk of getting the ‘motor boat’ sound. You can go with an integrated quad, which is what I did. Using a matched set E34L’s will get you the aggression and sizzle needed for a good high gain amp and will be complimented by the deeper low end of the 6L6′s (which will also smooth out the shriller high end EL34 types tend to have)

“I’ve recently began reading a few newer articles like this one and I see a lot more positive feedback from people who have retubed there V3′s but again not enough demonstrations of the results. If you could put up some music/videos I would deeply appreciate it. Thanks.”
–As I write this, it’s 1:00am Sunday morning. I will have a video for you sometime later today

But yes, you are correct: many players will create their own custom gauge set through buying single strings or mixing and matching sets. The Yngwie set I mentioned in the article seems to have followed this formula. I was never one for taking my experiments quite that far.
