Actually the famous GLB preamp is still available. After a couple coporate buy-outs the new company is called Simrex and they still sell the original GLB unit....and the even offer and amateur radio discount. Here is the web page..... _http://www.simrex.http://wwhttp://wwhttp://www._ (http://www.simrex.com/site/products/special.htm) Dan Hancock N8DJP The GLB units are excellent but they have no resemblance to the ARR preamps. To be fully effective, they need to be fine tuned with a tracking generator. They are essentially zero gain preselector devices that are more like active cavities than amplifiers. The ARR preamp is also an excellent cost effective unit but it is a relatively broad device and is more vulnerable to overload. Another short suit is that it's easy to blow the Gasfet without taking the precaution by griefly grounding any antenna connected to it to eliminate static spikes.
