Model PL Stereo Tube Preamplifier

DIY-K-PL

Here is a Stereo Tube Preamplifier Kit that is easy to build, and is just fun! The Tube Preamplifier utilizes a 5670 triode. The Preamplifier is compatible with all "L" Series Amplifiers, it gets its B+ and filament voltage from the Amplifier board and can provide 10 to 30 db of gain.

The PL Stereo Tube Preamplifier comes in kit form (K-PL). The kit comes complete with all the resistors, capacitors, tube, circuit board, and necessary hardware for mounting on a "bread board" provided (which is compatible with the amp you purchase or have previously purchased).
