Title: Singer SPA-100 Post by: ve3bbn on March 12, 2010, 09:28:04 AM Greetings all, I was wondering if anyone found any info on the Singer SPA-100 spectrum analyzer? I have also picked up one but the light house tube is defunct and I don't know the number of the tube. Any manuals ,schematics etc of the above would be greatly appreciated.
