I bought a Vibroplex original model from another ham who did not like it. It was 1953 and I was a novice. I did not like it either. So I ground down the width of the spring. Then used 4 inches of copper tubing over the end and pinched to fit tight. Then I used a big fannestock clip with some big solder wrapped around it to vary the speed. It would send slow but also worked good at 35-40WPM. Wish I had a picture. I sold it 5Yrs ago. Yep we enjoyed the video clip of the three bugs. I have heard some bad sounding bugs lately. Either poorly adjusted or perhaps with heavy spring. ( OK it could be the operator) 73 George/W2BPI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
