Box 773, Columbia, Mo. 65201 for 24 hr. shipment or 10% off. Their no. is Toll-Free 800-325-2595.The following are answers to questions by readers, which for lack of space we must answer this way. A red box duplicates the coin denomination tonec of the new "fortress phones"... If you have problems getting maximum volume from your box (issue 12) try reducing output capacitor to 2 mfd., and raising feedback resistor of op-amp to 10k or greater... Proper volume is when box is just too loud to be comfortably pressed to ear. .. A five station telephone can handle 5 incoming lines, but does not automatically give you 5 lines if you hook it up to your single number. ... We've heard you can turn a touch tone phone into a Blue Box, but it appears to be impossible... Thanks case... Blue box detectors are being made, and until we know all they detect, we'll say that use pay phones to be safe.
