I have just modified the home page for the Glowbugs web site to reflect an added choice for "Modifications and Upgrades". In that section I have put all the Heathkit service bulletins, Optimizing the HW/SB-101, HW-101 tips, and the complete SBM-102-1 mod for the Miller Effect. If you have trouble with it, let me know.
