Ver Halen finally picked a tube....

after a few years of us working out schematics and ideas about his amp, Jon finally decided on the copper plate GM70... the breadboard work has been done.. time for chassis decisions.. on this one, since Jon is an accomplished (you'd better be!) woodworker, he wanted to do the chassis work... I only have to supply neatly wired, good sounding, boards... great for me.. all the more time to spend playing with the circuit...

pic is of a quick sketch of the power supply... and if you have to ask what the blue tubes are, you are off the blog!



  1. What is the blue things ??? Kind looks like a light bulb.

  2. I know who you are!!!! no tennis balls for you!!
