I'm finding that if you're looking for any heatsink that there are
zillions of places to pick one up and that if you are looking for
a particular sink that it is a futile task. With a little help
from my friends, I'm putting together the mosfet amp in the 2006
handbook and I've pretty much secured everything on the parts list save
the heatsink. It is the same unit that was used on the original FARA
amp as well. Anyone have this beast in the junk bin or know of a
purveyor who might?? I've scoured the web and no joy so far. The sink
is an AAVID part (#244609B02). Thanks in advance all.

Apart from some teflon wire (thanks again Pete), Mouser had most of what
I needed. Unfortunately, they no longer carry said heatsink. Thanks
though. Other ideas ??

===================================
For large heatsinks (perhaps not precisely the type you need ) flea
markets will be a likely source . Otherwise there might be an
electronics surplus store in your area .
Some time ago someone gave me a clapped-out (probably illegal) CB
amplifier (of Italian origin) with a heat sink to suit your project
.........however I am in Scotland- UK ,otherwise I would be happy to
send it to you .

Thanks for the thoughts Frank. I would not have guessed this before the
fact but I'm finding that tracking down / scrounging these bits and
pieces is actually fun (I am also sure that there is great probability
that I will rue these words...). Thanks again all.

if you know the parameters of the heat sink in question, a search through
these pages on the Mouser website should give you what you need. there are
several pages to go through, so you do have your work cut out for you!

Thanks for the advice. Mouser very nearly had a replacement. The unit
has horizontal fins instead of vertical and as my application is
convection-only, this likely tips the balance on effectiveness (safety).
Did find another site and it looks like a good one. It's Nebraska Sales
and Surplus. I've purchased from them before and have no complaints.
Thanks again for the quick replies.

I don't have a copy or the 2006 handbook, so I can't visualize the heatsink that
you're looking for. Low resistance heatsinks are usually made from extrusions
and can be any of a number of designs.
Is there a photo in the article that shows the heatsink? Possible for you to
post a scan of it on alt.binaries.schematics.electronic? Also, the dimensions
of the heatsink would help to find a substitute and source.
If you're in or near the central Florida area, Skycraft usually has a couple
bins of heavy heatsinks that might suit the job. I bought a couple that
calculates to about 0.5 degC/watt each about a year ago. Last time I was in the
store (in February this year), they still had about 10 of them on the shelf.

You mentioned that it was also used on the FARA amp. Is there a link to a web
page that describes (hopefully with a photo) the amp?

Cheers!!

Oh, that's ok Gary. I hope you find the one you are looking for. Most of
that stuff from Surplus Sales of Nebraska came from the Inventory Disposal
sale from Rockwell-Collins, which means that it is of good quality.

Thanks one and all for the suggestions. Started soldering this evening
so there's no turning back...
