    Cool looking 6L6 amp! Has a deco design to it, and a very cool look
    when running with it’s backlit logo and power light. Would be a great
    harp or guitar amp to explore with. This is a Lafayette CO-ORDINATED
    Sound System model 419.

    I went through this and replace all capacitors. This includes all the
    electrolytics and paper caps. I also replaced all out of tolerance
    resistors. The output transformer windings tested good. I replaced
    the power cord with a modern 3-prong cord for safety. The schematic
    originally called for a .5 mf cap from line to chassis ground. I
    removed this, but you may wish to install a modern noise/interference
    scheme that is much safer. With the grounded chassis and modern
    electrical power, this amp is safe as it is now.

    I replaced the 6SC7 and 6J7 tubes tubes, the 6L6G and 5Y3G are as they
    came and work well. One 6L6 had lower emission than the other, but
    works very well. You may wish to experiment with 6L6’s anyway.
