Can this be Upgraded?

That sounds like an idea. I'll throw it in my car tomorrow & go from there. If I have the time, I'll take the clamps off of the devices & see what they actually are too.

Hi

Transformer is not that small, lots of wires on it... if you would increase freq. of power supply, it would be able to put more power out, but wires on it are probably limitation, not core itself

But I wouldn't change this amp in any way, since it works, and if it works don't fix/change it...but do as you wish

As crazy as this might sound, I have found it fairly easy to get in contact with the engineers of different products.

With a little research you could likely talk to the person that designed the amp and ask why they opted to not use all the FETs on the output. It was clear that they had either the "intent" OR "option" to add more fets. This is where it is a gamble, as if they had intent and didnt, there is a reason. This is likely not the only prototype and the ones with all the fets may have not worked properly. If they had the "option" then it might be OK but just not justify the cost in production VS a gain in performance.

This would make me think that by adding the fets you will make the amp work poorly if the engineers had intent or that it would be an unnoticeable gain if they had the option.

I say do it, I would like to know what happens……(its not my amp!)


BTW: I am somewhat new to doing this sort of thing but I could see a manufacture opt to use fewer fets of a higher value then the original design that had more fets of a lesser value. THis could be a cost cutting measure that equaled performance and lowered production times. This could also explain why there is fewer fets on the board. But take into consideration that I have no clue what I am talking about.

Well, I doubt I'll be able to find the engineer(s). Quad Audio as best as I can tell is an install shop that wanted their own brand. I'm betting that it's a somewhat generic design, but I can't find it anywhere on ampguts. Here's Quad Audio's rather sparse site:

I'm thinking I'm going to do it, because there's nothing to lose anyhow. I've got tons of working amps, so I won't be out an amp. I've also got tons of broken amps, so why not add to the stack.
