Default cooling of TDA

Congratulations for this excelent project! I am going to replicate this DAC too. In my hifi rig, P. Daniel's shigaclone starving for a good DAC . At the picture showed at the 1st page, I can't see any cooler. I guess, in the absence of passive cooler at 8.3V the TDA chip get very hot, or?!

Hi

I measured the temp on my DAC chips ( se page 28 ) and after about an hour of playing they are about 60° C at 8.3v

I do not think that there has ever been a kit, Peter just explained and showed the schematics

I don't think so, this is old technology and I don't expect much sales.

If I ever need to build one, I'm using p2p methods or modify someone else's boards

Potentially really noobish question since I know very little about digital stuff... is there a way to get the clock and slave the transport to it?
I have a shigaclone transport (Tibi's 1st clone, now awaiting for the MK2) which requires 16,9344MHz
