SVT 4 Pro

If it were me, I'd use the lightest rack I could possibly find. I don't know what rack that would be, but in all likelihood it would be something like an SKB...made of hard plastic. And I would do my best not to have any other stuff in the rack.

How much does the rack mount case weigh? the svt weighs around 40 lbs, an skb 6u weighs about 15 lbs

 

Ya removing the power conditioner should not be an option, you think the svt 4 and the power conditioner would fit in a 4U rack? this would do it, weighs 12 lbs

i dont think the weight and heat output from the amp should be a problem, these open up at both ends and if really needed you could drill some vents..

 

There's these trolly type rack cases but they're heavier and more expensive

You really don't need a power "conditioner". They're all just glorified power strips until you get into the serious $1000+ category. That said, I used to have one on mine when I used a rack because of the convenience factor. But it's not necessary.

 

Just last weekend pulled my Mesa Bass 400 out of its permanent home, which was a Mesa road ready shock case. Immediately reduced the 75 lbs. weight almost by half. Now the head travels naked, and I carry a very light 2 space rack holding a power conditioner and and Alembix F-1X for back up. And everything rolls in and out on a light weight but fairly heavy duty cart.
