Richard Gray 1200 Custom blew up!

post #1 of 12
Thread Starter 
Wow my unit wasn't working on one side anymore so I decided to check the fuse. The cover came off but the fuse stayed inside. I tried taking it out with pliers but it was just pushing in further. So I took off the top and this is what I found...






Checking with my dealer to see if it's still on warranty. If not, is this an easy fix? Just the fuse should of blown, not the whole thing!

In this case you'd just replace the fuse holder, which are available in many styles on the web and at an electronics parts supply store.

This is why this stuff needs to be UL listed. I don't know if the RGPC unit is or not. But this could have resulted in a fire.

Another observation: Note the "MTW" rating on the red wire in the middle picture. MTW is Machine Tool Wire and is listed for the internal wiring of machines such as here. My point is that this wire is as common as lamp cord. Now it's just fine for this application but isn't it interesting how a foo foo power conditioner just uses the cheapest wire available for the job at hand.

I never understood power isolation/purification components, especially at the $2200 price point for the 1200 custom unit.

Thanks, I'll see if it's still under warranty. My dealer said he was sending the pics to his distributor.

I couldn't tell you if it was. I agree with the fire part. It's making me concerned now even if it does get fixed.

Well this was the first and the last.

It is both CSA and CE rated and claims compliance with UL 1449: http://www.richardgrayspowercompany.com/pdf/parallel/1200.pdf. So there is no issue there.

I wonder if the wrong fuse was put in there.

I've had it for 3 years running on the same fuse I bought it with, new in box.

Well it says it's "compatible with UL1449" Now isn't that just like an high end audio product blurb!

Translation: "no our products are not UL listed but we are compatible with their standards" WTF?

However it does show CSA as well as European CE, and IMPE, that's good enough.

P.S. For those that care, UL1449 are the standards for surge protection devices. From my research, this came about in the early 2000s after reports of power strip meltdowns due to partially shorted varistors.

Finally got a reply from my dealer asking me to bring in the unit for repair.

It is interesting that only one end of the fuse is charred. This means the problem was not that too much current went through it or it would not look so clean at one end.

What I think happened is that the end end of the fuse was not making a solid connection. As a result, it overheated and caused the terminals to melt away over time. Did it have a screw cap? And if so, was it loose? If not, then this is a defective fuse holder.

Either way, make sure they don't charge you a dime. It is clearly a manufacturing problem.

for what you paid for this amp, he should be sending someone to pick it up and bring a spare for you do use while it is gone!

BTW total agreement with the3 posts above mine.

No they aren't charging me, thank god. I would of thrown a fit in the store if that was the case LOL. For the price I paid for that thing....I agree with your assessment. I don't think it was a current spike or anything like that.

Ya seriously! I don't think I'll ever buy a power center this expensive again!
