You SAID you're on vacation; but I KNOW you, man! You're probably still at home, hacking on that PDP-8 you got at the hamfest. Well, forget that old crap. THIS IS IMPORTANT! The boards for "Project Z" arrived. PLEASE get them assembled and working NOW! If we don't have something INCREDIBLE for the show, we're dead! I already talked to Jim Warren, and got a great booth at the show, right across from Heathkit. I put everything in the box we could find. You've got the boards (aren't they GORGEOUS?), all the parts (I hope!), and every scrap of paper Chip thought you might need. Crash also burned his latest monitor program into the EPROM, and wrote some docs on it. Remember, this is going to be the world's first POCKET COMPUTER! There's no time to get a custom case; so for now just stick it in an Altoids tin. It's a hacker classic, and "everyone knows" you can't make a computer that small (but WE can)!

  • Lamm Industries Model L2 Reference Preamplifier the Technology
    November /December 2005 Lamm Industries Model L2 Reference Preamplifier Taking the proverbial "Road less traveled." Review By Dick Olsher In my audio lexicon, the 'Reference' appellation is reserved for components that represent the state-of-the art (SOTA), or at least a cost-no-object attempt to metaphorically scale the SOTA mountain in a particular category. Such components hold up a mirror to the music, reflecting the heart and soul of the program material onto the listener. Reference class gear should represent the closet approach to live music — a serious attempt to bridge the gap between reproduced and live music. Lamm Audio's chief designer, Vladimir Lamm, a man with an impressive portfolio of high-end creations, apparently rates the L2 Reference as one of his best. Thus, as you can imagine, my expectations of the L2 Reference (L2R) were quite high. Had the L2R arrived on my doorstep in a 15-pound cardboard package, I would have immediately been suspicious of its legitimacy to reference status. You see, as I will explain shortly, heft is important in amplification. In fact, the L2R arrived in two wood crates, each weighing nearly 40 pounds. Great, we were off to a good start! This is a two-chassis affair, with a separate power supply. Features include three RCA inputs, one tape loop, an output signal phase switch, and both balanced and single-ended outputs. The signal circuitry layout is dual monaural to minimize channel crosstalk, which explains the duplication of controls for the left and right channels, including dual TKD stepped-attenuator volume controls.

  • AA5 AM Tube Radios on 240V AC
    AA5 AM tube radios on 240V AC http://pw2.netcom.com/~wa2ise/radios/aa5240v.html Designing an AA5 AM tube radio for use on 240V AC 5ive methods, just below is the "heater current in series with the plate current" method. Second method is the "higher B+ on the 50L6 audio output tube, AC cap in the heater string" method. A third is to use a capacitor in series with the entire radio circuit. And a 4th radio where the usual tubes are replaced by those whose heater currents are 90 (117L7) and 70ma (three 26x6). Yet another using 100ma heater tubes . My objective here is more of an electrical engineering "what-if" than just being a way to convert an existing radio. Like a "How would the engineers at the XYZ Radio Corp design an "AA5" for sale and use in 240V countries". Given a large enough production volume, the cost of the 26V tubes used in radio four would come down to nearly that of the common AA5 tubes. The diagram on the right shows the modifications done to an otherwise standard AA5 AM radio circuit. How a manufacturer might have designed an AA5 for 240V AC countries. If it is desired to convert a normal "All American 5ive" 120V AC AM tube radio design to run off of 240V AC, the following is a relatively low energy consumption way to do it. Especially for the collector living in Europe or other parts of the 240V AC powerline world. Olympic back in '53 made an adaptor cord, which consisted of a 430 ohm power resistor around 40W in series with the entire set, for their AA5 sets.

  • The History of the Heath Companies and Heathkits: 1909 to 2019
    The History of the Heath Companies and Heathkits: 1909 to 2019 © 2019 Erich E. Brueschke, KC9ACE and Michael Mack The genesis of the Heath companies can be traced to ideas preceding the founding of the E. B. Heath Aerial Vehicle Company in 1909 by Edward Bayard Heath. Although Edward Heath was primarily a figure in the very early days of aviation, he recognized that meeting people’s needs and giving them a sense of participation greatly enhanced outcomes. He was widely known as a pilot, instructor, barnstormer, and manufacturer in his day, and as the progenitor of the kit concept for airplanes, his influence on the later Heath Company that sold Heathkits extended well beyond his death in 1931. This paper covers the history of the Heath companies from inception in 1909 to the present day. Built on the tenets of “hands-on learning,” a “build-it-yourself” approach, “cost savings,” and “customer ser- vice,” Heath Company became the largest manufacturer of electronic kits in the world. Photographs and information on a select number of individual early kits are included to assist in understanding the post-WWII days of rapid changes and the growing pains the company experienced at the start. From 1947 to 1992, the Heath Company sold millions of electronic kits. The factors responsible for this success and its decline are discussed. Some of the key factors that led to its decline were beyond its control—for example, the company was sold many times to owners with varying degrees of interest in support- ing the company. As of December 2018, the Heath Company was located in Santa Cruz, California, for design and manufacturing, and Ottsville, Pennsylvania, for operations.
