Stereo phono preamp using JAN 6418 tubes

Here is a nice little stereo phono preamp using a pair of JAN 6418 subminiature tubes. This design uses very few components and adds a nice bit of extra oomph and tube tone sparkle to your input signal. I have tested on turntables and cassette decks with great results.

Using an IC7660s as a charge pump to bump the 9-volt power up to 18 volts adds an extra bit of sparkle to the sound. The IC7660s can be omitted as this design can be run at 9 volts. The 6418s are rated for up to 30 volts and tend to sound better and better the more voltage you run to them.

If you are getting signal noise, try a ground loop isolator. This design doesn’t like dirty power.
