Hi all,

Instead of mounting the TO3 transistor ont he flat part (bottom) onto the
heatsink, do you lot recon I could drill a large hole in a heatsink and
mount the can side into it, and put heatpaste around the can and screw it
down from the top ? does anyone have any thoughts if this would work as good
or worse than the bottom just being bolted to the heatsink ?

The transistor I have in mind is a 2N5038, a little higher wattage than the
3055, I plan to have around 50watts constant disipation, it should be ok,
right ??

Thanks
chris
