A pleading request to manufacturers of amplifiers and preamplifiers.


 At this time I would like to make a pleading request to manufacturers of audio electronics.  Please in the name of all that is holy stop putting sharp heatsinks on the outside of your devices. In the decades that I have been involved in this hobby the collected skin that has been carved from my toes, ankles, fingers, hands, wrists, forearms, etc. is equal to the combined weight of a professional football team. The blood I have lost could have saved the lives of 100 hemophiliacs. I have come to fear my own devices as if they were the vampires or werewolves of legends. Can you not round the edges, put covers over them or locate them inside the case? Freddie Krueger has not inflicted as much carnage as the combined horror of all this equipment. The combination of 50 lbs. of transformer weight and 6 square feet of rabid heatsink is a guarantee of laceration when moving any of these monsters. So if anyone out there can hear me I am begging, pleading, will pay for, changes to this abominable practice of covering your products with ravening metal blades lusting after our flesh.Thank you.

David Hafler got the message. I was a Hafler dealer and I loved the sound of the products, esp. the MOSFET power amp the DH200. I still use 2 of them. But we complained about the very sharp* fins so the biggest improvement (IMHO) was the beautifully rounded heatsinks on the DH220. I have 5 of those and they are all still warming up my home theater. The MOSFETS do run hot. Reliable... of the 7 amps (35-38 years old in use 40-60 hours/week) only one issue occurred. A defective fuse. NOT blown, the fuse wire became detached from an end cap.
* VERY sharp. I assembled over 20 of these for one project and still have painful memories of having to move them out to the client’s home.
*L*  For those of us on blood thinners, I can relate to these tales of woe...

Fortunately, my current (no pun, no) amp doesn't have exposed heat sinks....and at 50+ lbs., isn't going to be moved in the near future.

And, also fortunately, I clot quick.  Which is why the thinners, so there's an ongoing battle within my hemoglobin system...

I'd suggest welder's gloves; thicker than typ. leather.  Although I've been advised that a racoon can bite through them.  If your PA is like a cranky racoon, well....you're screwed.  Go to stainless clam shucking gloves with an overlay of leather for grip....

Or hire a young relative whose not afraid to die....*LOL*
