Anodized Aluminum Heat Sinks

Heat sinks received

Good News,
The heat sinks arrived today.

A picture is attached, showing the heat sinks(which look really nice), as well as the drilled & tapped holes for mounting. I measure 7.5x5.4x1.25" and the fins are 1" in length.

The more I research heatsinks, I'm thinking the estimate of 0.5deg/W that I was given may be optimistic; apparently it depends upon the ambient temperature. I am pretty confident, however, that two of these used together* will be fine for the 10 devices of an extended Leach amp(which is a class AB amp rated at about 120-150W into 8ohms).

I'll be packing them up and hope to mail them out on Monday.

Any questions or concerns, give me an email.

Thanks and Holiday Greetings to all!

-Chas

* two used together measures 10.75x7.5x1.25"

These were military surplus, purchased online (I found using a Google search); Unfortunately, they're all gone, and the seller does not expect to get any more.
You might check with Apex Jr. - I believe they have some large gold anodized heat sinks at a fair price.

Regards and Happy New Year! :cheers:

Update

Update-

Turns out that one request for these heat sinks was never paid, after waiting several weeks.

If anyone is interested, I have 4 pcs available; unfortunately, I lost $$ on postage(and Paypal) last time.
Plus, the cost of shipping went up 1st of the year, so I'm asking $25 per pair including postage(within the lower 48). Still a good deal on these really nice heatsinks ( I'm using a pair in my Leach amp).

Please E-mail me if you want them, and I'll give you my Paypal addy.

Update:
Both pairs are sold; however, I still have one single piece I was saving as a spare.

Turns out, after cutting/machining my two other pairs, it looks like I won't be needing it.

If anyone can use a single 7.5x5.4x1.25"heatsink, please let me know. I'm asking $12 including postage within the lower 48.
