I've got dozens of these switching power supplies, the cases and heatsinks look like they might be useful for DIY GC cases. They measure 6"x 10" x 2 1/4" ... Cigar box size.
Any interest? |

| I'm interested not so much the boxes as I am the heatsinks. Are they able to be removed from the box? How much are you looking for them? |

| Is the digital RS SPL meter shown in the picture accurate at the lower fequencies? I've read that the analog one are inaccurate. Sorry about this other subject post. |

JCoffey-
Yes the heatsinks are removable, about 16 screws altogether. The plate is almost 1/4" thick, the fins just shy of 3/4".
I thought they'd make a tidy little GC case, without parting out the whole thing. But you're right, the heatsink is prolly the most useful bit (aside from the cute little green power light.)
How many do you want, and how much do you want to spend?

Sorry? How would I be sure? (Not trying to be facetious)
The meter dial does only go to 60db, however I get readings that seem reasonable well below that. Its the funny little changes in HF levels where my head and ears get kinda twisted up, where I don't think it's accurate. :^)
I also have some other cases, dual 10"x20" mounted on Pro audio rack shelves. No heat sinks there, but yes, I'll part out just the shelves.
If anyone's interested, I can post some more pics. Or you can email me at

Fcel,
IIRC they use the same element, so no. The analog is a more stable unit & the most popular for that reason. Oh ya, & it's cheaper too :)
You can mod the SPL meter to be spot on though.
This also might be helpful:
*** Radio Shack SPL Meter Correction Values ***
To find the corrected values just add the figures below to your results:
10Hz add 20
12.5Hz add 16.5
16Hz add 11.5
20Hz add 7.5
25Hz add 5
31.5Hz add 3
40Hz add 2.5
50Hz add 1.5
63Hz add 1.5
80Hz add 1.5
100Hz add 2
125Hz add .5
160Hz add -.5
200Hz add -.5
250Hz add +.5
315Hz add -.5
400Hz add 0
500Hz add -.5
630Hz add 0
800Hz add 0
1kHz add 0
1.25kHz add 0
1.6kHz add -.5
2kHz add -1.5
2.5kHz add -1.5
3.15kHz add -1.5
4kHz add -2
5kHz add -2
6.3kHz add -2
8kHz add -2
10kHz add -1
12.5kHz add +.5
16kHz add 0
20kHz add +1 |

cdoggy81,
What you have shown is exactly what I have read somewhere else. I do own the analog version of the meter. As you can see, below 50Hz, one has to do a lot of mental calculation or else the meter is giving misleading information. What I was hoping is that if the digital meter has the lower freq corrected already, I would just buy one.
And yes, I'm aware of the circuit modification and I do have all the parts ready to modify the analog meter to correct the lower freq reading .... but did not get to modify it for the longest time .....
x.onasis,
Sorry for posting other topic here but hopefully this would also give this thread more exposure. |

I'd be looking for 8 total (maybe even 12) As far as cost, not sure. How dinged and nicked up are the fins and the anodizing?
Parting out can be a pain to take a part, and dispose of the leftover stuff, but I bet it saves in shipping. How heavy is each case roughly? |

The cases unstripped weigh in at about 3 lbs. Stripped about half that. The scratches and dings vary, from none to slight, with a couple dented pretty good as they were thrown in a box. I could select them out as best I could, if you want nice ones to show.
I was thinking for about $15 or so, they would make a nice case to give shielding, mounting, and something to attach some nice side boards to for a pretty little case.
Shipping is a funny thing in this price range. Parting out and boxing too. Distance makes a difference, but stripped-out, the costs are only a coulple bucks less, but as far as recycling the rest goes, I'd prefer to do it here, as this is what we're all about. |

| Thats not too heavy then. I wonder how much heat they can disipate... |

I'll take 2 - 4!! Complete! Not stripped out!
E-Mail me with price per unit and shipping to Zip 92626
Thanks, Jay M.

Just wanted to note that the heatsinks weighed in at 2.7 lbs.
Thanks to all who ordered some, and I look forward to seeing the completed projects.
BB in a week.
Planet10 may soon have some info on some toroids not pictured. |

| Do you have any left. I am looking for one as well. |
