One thing is that when this is all boxed up without ventilation it gets hot inside. I've just done that to my Si570 controlled SR 6.2 Lite and realised that the warm up drift is far greater. I have put a couple of fins on the regulator (I'm one of the oldies who don't like hot semiconductors!) and wonder how hot it would get without any heatsink. It will probably not bother most users but I am considering moving the regulator to a heatsink on the side of the box. 73 Alan G4ZFQ
