Hi
I had a question regarding heatsink selection. I'm building an single channel of API312. My power transformer is a Antek 10VA, dual coil 15V. To make the 48v, I'll use the voltage tripler of my psu, which would get me around 64V, in the case of. I got about 16V to drop across an LM317HV. For the bipolar rails, about 6.5v of drop across LM317/337. Do I really need an heatsink on each regulator? Let's say the 48V rail would get warm, is a little TO-220 heatsink would do the trick or I would be better of to go with one big ass heatsink? Thanks
