Hi there,
I recently found a box of about 150 old 12SN7 GT tubes from various brands.
I was wondering if anybody knows of a good preamp circuit that uses this?
I'm a guitar player, and I have experience building overdrive circuits. When I found these, my first thought was to use them to make a tube overdrive guitar pedal, but from what I've read, these aren't very high voltage. If I could use them as a microphone preamp, or perhaps a tube phaser, I'd be very interested in that as well. Hoping that someone has some insight into this.
I've never made anything that required a tube (or transformer) in it, so that will be new to me but I'm extremely familiar with soldering, schematics and using the various other components that would make up a typical circuit.
I did find one preamp schematic online, so I will likely be building that first, just to see what these will do.
Thanks for any tips/insight
