Straightening Bent Fins

Nice video pbn! I did a search on "Bent Fin" and it turned up many stories about others who have had many episodes like mine, most were way worse. And, looking at used amps, it's not uncommon at all to see one with a slightly bent fin from some previous encounter. It happens way more than it should. 

Yes it was in a factory box, but the foam padding failed, and the amp twisted in the box. And no it wasn't bent in the seller's photos.  This thing weighs 130 lbs, I know they weren't ginger with it. And the amp works fine, sounds amazing! No internal damage that I can see. Perhaps a new heat sink would be the way to go? If Krell even makes them or has one to sell. It's an FPB-300, not the lastest model for sure. 

I was thinking more like Erik suggested, possibly some wooden shims to prevent scratching. And applying some heat. No, not a torch or anything, just a heat gun like I use for shrink tubing. To help prevent cracking. If it's 200 degrees it would be a lot less likely to break. If my only other option is buying another, then I have nothing to loose? If, they have another. And what is connected to it? Some heat sinks have transistors attached to them, others are only against them. 

But it is a testimate to the solid build quality of this amp! It's like a tank, the rest of it is completely unharmed. No rattles or wracking, of course it feels like solid lead anyway. Wow it's heavy! At some point they should think of separate chassis, and I guess they do? I don't have to worry about some theif snatching it up and running off with it! 

so thanks guys, I guess my next step is to contact Krell. 

After I have lived with the amp for over a week now, I am not quite as upset about the fin as I once was. But I'd still like to fix it, to maintain the value of the piece. And there are 3 heat sink plates per side Jetter, the 300's have 3 per side and the 600's have 4 per side. 

Im not sure, but the heat sinks on the later FPB models may be the same? On the C and Cx models? So perhaps Krell will still have them in stock? Anyway, I've sent an email to Tech Support at Krell to inquire about a new heat sink, I suppose it's a holiday weekend for them, so hoping to hear from them later this week. I was an electronic tech in a previous life, so am confident I can make the swap. 

You may be right ebm, I'm sure it affects the value. But the original exterior box was undamaged, and I guess I wasn't up to the hassle of returning it over what seemed like a small thing at the time. But, I love the amp, it sounds amazing, and other than that fin I am very happy with it. If it's the last amp I ever own, then it's accidemic.

I emailed Krell, and have not received a return message. I have the worst luck with manufacturers. Everyone goes on and on about how great Krell is, and they won't even respond to a polite, simple question? I'll call them on the phone, perhaps I'll have better luck.
