I have found CHEAP heatsinks that fit the AMP7 or AMP15 like a glove, and they look nice too! The size is almost exactly the board size!

You get just the block, not the plate on the side.

The cheaper one is 15mm high, so I think that is the best choice.

They may look small, but believe me they cool more than enough....

Just tap and die thread in it using Krilli's drilling template and you're in business!

I've found these two heatsinks.

The first one is identical to the one proposed by V-Bro

Distrelec Heatsink 1 (https://www.distrelec.ch/ishopWebFront/catalog/product.do/para/keywords/is/SK_105_100_SA,SK105100SA,Fischer_Elektronik,K%C3%B Chlk%C3%B6rper_100_mm,Leiterplattenk%C3%BChlk%C3%B 6rper/and/language/is/de/and/shop/is/CH/and/series/is/1/and/id/is/01/and/node/is/DC-51117/and/artView/is/true/and/productNr/is/650819.html)

The second one is probably too big, but its cooling capacity is very good.

Distrelec Heatsink 2 (https://www.distrelec.ch/ishopWebFront/catalog/product.do/para/keywords/is/SK_136_150_SA,SK136150SA,Fischer_Elektronik,K%C3%B Chlk%C3%B6rper_150_mm,K%C3%BChlprofile_0,75_K_W/and/language/is/de/and/shop/is/CH/and/series/is/1/and/id/is/01/and/node/is/DC-22575/and/artView/is/true/and/productNr/is/652423.html)

Nice Gigi! Although there is no need for much cooling capacity, these amps would already feel fine on just a flat aluminium plate in the size of the board...
