Gentlemen: Many thanks to all who replied to my post about the SB-1000. I
looked further into the grid bias circuit, as was suggested, and of
course, found the 7.5 V Zener fried. Ordered one from Ameritron. Don't
know why I didn't think to look at this along with the other
components-advanced senility. Praying the tube has something left-got a
price of $228 for a 3-500Z. Charlie. K0GPF
