I was checking out the schematic from the one-tube amp that was posted here http://www.guitarworld.com/diy-musician-build-your-own-one-tube-amp... and have a few question. In the explaination of the build the writer says to add a .05mfd 200V Cap in the position shown on the schematic by an X. Will doing what is highlighted (in the attached picture) along with adding a grounded plug to the amp prevent electrical shock? Is this a way around the Isolation transformer? Or what exactly where they trying to do with adding this cap?
there are plenty of safe amps out on the internet to make. this looks very dangerousAC mains direct to the heater element of the valve.
No, there is no way around an isolation transformer in this amp.
thanks for the link David. what a nice simple circuit. might have to rethink the preamp in my amp rebuild...
have you built one? and if so does it have a nice crunch tone?
You have to know what your doing with tube amps. The tubes can produce 300 to 400 volts that can stop your heart very quickly. Read up on tube amps circuity before building anything with a tube in it.
