I sometimes hate this hobby... Marphy`s Law constantly works against you, every little "trick" you learn hard way, and sometimes I`m not that patient... In the last three days I worked on the small PCBs for the CCS... I somehow ruined three prototipes so far, break nice 0,8mm bore, etc - but the fourth looks promissing. I`d (probably) post a picture in a day or two. In my prototipe I put one transistor on the upright heatsink, and other from the other side of the sink ("shield"), 90° angle between them. I was tempted to put about 50 various "stoppers" in the first version, but finally I`m building it simply, we`ll see. Unfortunately, it`s the MJE350/BC558B/LED CCS and not 2 x DN2540, but the principle can be seen. When I think about it - all that capacitances between the PCB traces just call for troubles, arghh...we`ll see.
But, looking at the "Playboy" and mess with real women is not the same, the former is much easyer...bad joke again...Probably all that acid fumes...
