Hey John,

Was admiring your handy work in the pic you posted, and found a point of concern. The tabs on your big electrolytic cap in the photo seem a bit to close for comfort to the chassis. It may be a optical illusion but I thought I'd mention it, particularly as the -ve will be earth but the two +ve terminals will be at something near 400VDC. In my books the greater the distance they can be from the chassis the better. It may be a simple a fix as rotating the cap in its mount until the +ve terminals are as far away from the chassis as attainable.
