Thank you all so much for making your splendid designs available on
the Web. I took Mr Pass's advice on the need for adequate heatsinking to heart, so I hope this
somewhat radical solution will do the trick. Tomorrow I will borrow a friend's Variac to start the
inauguration ceremony (at present the power supply electrolytic capacitors are only 35V working, so I
must tread gently. Some modification may be necessary here before I can power-up fully).
