I am going to be building a pair of mono blocks using the latest iteration, V3.1, of Colin Wonfor’s SECA PCBs. I am aiming for the maximum output power of 40 wpc. I am currently getting quotes for toroids.
Each mono block will require a heatsink rated at 0.1 degrees C/W or better. That’s a huge amount of heat dissipation. My plan is to buy the heatsinks separately and then have a local metal fabricator make the enclosures incorporating the heatsinks. Perhaps I’m just lucky but there are lots of metal fabrication outfits in the West Riding.
Next week I am speaking to Julian Cavalot of BAL Group. He is their heatsink expert. Following that I will decide whether I am going to use just passive heating or incorporate a quiet slow speed fan into the chassis so that I can use a smaller heatsink.
I’ll post further updates as things progress.
