Add-on heatsinks for Audiolab 8000A

I usually rotate the amp in-use (in the hall) every once in a while. Currently it's the last series of UK made Audiolab 8000A with 'F' in the serial number.

The external casing of the 8000A was running quite warm in the local tropical weather. Hence I search for suitably large piece of heatsink to assist with heat dissipation - inspired by the design of the casing on my long ago Musical Fidelity X1A.

After checking a number of websites, I had to give up my initial idea of acquiring a single largish  heatsink. Discovered that could became a rather costly exercise, with possibly pricey postage too!

About a week later, I came across a PRC website which had some attractive looking heatsinks on offer but these were smaller than what I had in-mind. Then the idea hit me - I could arrange several of these smaller heatsink(s) in such a manner that they could assist with heat dissipation from the critical areas of the 8000A, as if a single large piece of heatsink was deployed.

Each heatsink is anodized aluminium and measuring 150mm x 70mm x 11mm. Used 6 of these heatsinks and arranged them (as per pix) with a spacing of 1-3mm between them. As most of the heat on the external casing were from the LHS of the 8000A, I arranged the heatsinks on the LHS closer to it's neighbour vs those on the RHS.

Aesthetically pleasing too, no complaints from the boss ... yet😁
