Deep surplus is great, I bought 10 closely matched from there and they worked perfectly.

It's nice that you want to do it. I have got a pair of them from one of you and now enjoy really good sound but it would be good to have spare ones. Just in case.

Baaaaaad Papa!!

take your time ...... and match them well

I hope to have soon (month or so) tried and tested LuDEF amp , so that will be another one worth building ..... even Veroboard-friendly

Hi

Iím working on a ZV9/F3 and need some guidance on where to locate the output device to maximize heat spread across the heatsink. 2 scenarios; one with devices far from each other and the pic they are closer.

Heatsink is fan cooled, 300mm (D) x 180mm (W) with 50mm fins. I have no clue if this setup will be able to stay below 50C while having to dissipate 150W (75W/ch)

Thanks for the advice

Eric

Is the right one better if the fan is located in the middle and blows less air on the side fins ?
