my amp mod (and a couple questions)

[jgcable]

Where are you playing where you need the volume of TWO full stacks?

I do the original band thing, and find that 1 50 watt tube halfstack is more than sufficient. I'm lucky if I can turn it up halfway before the sound guy bitches.

You guys crack me up...

+ 1,000,000,000

I wonder if he pays his roadies VERY well??

That heatsink is keeping your internals from a melt down. Mainly.. the output transistors. Mess with it.. and you will have a box full of melted and fried parts. You can't move it.. make it smaller or add fans to compensate for it. Thats not the way SS amps work bro.
Abandon your idea. It ain't gonna work.
Well.. actually it will, for a few minutes. Maybe even an hour tops.

You should buy a set of Tung Sols for that thing!!

I usually see Racer and immediately thinking it is Ron =) My bad

[horns666]

I think it's awesome!!!!

Put THREE in there and buiit in glory hole so you can fuggit!

That would be 1,050 watts of head!!!!


Heat Sink..Meat Pink..Shove your pud in there I think!!

All I can think of is that those solid state 350 watts just...can't keep up with ultimate tube power.

So, in short, listen to Ron.

I also don't get it. Why anybody would find a 350watt amp not sufficient is beyond me (unless you are the bass player).
Oh and it's pretty clear that you don't seem to have an understanding about your amp. So if i were you i would completely stay away from modding. The chances to ruin your amp are just way too big.

Also you say 1 fullstack isn't as loud as 2 full stacks (well yes seems logical) but then you say you want two amps powering one cab each. But this would then be 2 halfstacks. Why just not use 1 amp and two cabs like everybody else does ?

First off, yeah... Just like everyone else said. Keep the heatsink. Second, it is not a good idea to cram all that electronics in the same box. When these products are designed, airflow, operating temperature and many other factors are taking into consideration. It is very likely that you will not have a problem... Initially.... But, the wear and tear over time due to it's new operating temperature will start to take it's toll on your rig ending up with a plethora (Si El Guapo a plethora) of shit happening to you at very bad times. So, in short, listen to Ron.

...yeah, no offense, but I find this whole thing a waste of time and money. If you MUST run two heads, stack one on the other. you're just asking for trouble trying to jam 2 heads into 1 chassis, and it does nothing.

You should run both heads at the same time, 6 channels then! just use a A/B box and there's 6 channels to work with!
Looks awesome and great idea!!

If you still want to put both amps in the same head, you could replace the heatsinks with smaller ones and add a fan or two at the back. It definitely wouldn't work for mic recording, as the mic would definitely pick up the fan noise, but for live situations you won't be able to hear the fan over the amp. Fans are easy to come by, just check out any computer enthusiast store, like www.newegg.com . I'd guess that an 80mm-120mm fan would do fine. Of course you'll need to supply a 12V line to the fan.

Finding different heatsinks will be tough. Nothing inside of a computer approaches the size of an amp. You could always buy a bunch of smaller ones. In any case, the above posts are correct: if the amp didn't need heatsinks Crate wouldn't have put them there. Heatsinks effectively dissipate heat from hot materials.

There is one more option, but it's pretty crazy. Build a water-cooling system for the amp. It can get a bit pricey ($200 or so) but it's better than a heatsink and you could place it outside of the amp head. Just google it to find more information. It's a fairly common cooling solution for the overclocking computer fanatic.

Why would you turn the reverb up if it's unplugged? It's obviously not going to work unplugged, so leave the knob at zero. Either you want reverb or you don't.

I knew it wouldn't work unplugged, I just wondered what turning the knob up would do.

It turns out the only way to do this project and make it fit without serrious mods is turn the top amp upside down and mount it that way. the heat sinks would be fine and everything would fit...

I think it would look stupid with the top amp upsidedown though, so I might not do it.

Someone on another forum suggested I just throw both amps in a double live-in. Maybe I'll do that.

Even if there were enough space in the box, adding an entire second amp in that enclosed space will not allow proper ventilation. You will most likely end up killing both amps.
