This is a full rebuild kit for the Rockola stereo tube type amplifier commonly found in models 404 and 408.  It contains every capacitor in the amplifier, both coupling and electrolytic, and a schematic diagram.  TUBE KITS are also available for this kit, or nearly every jukebox amplifier, inquire.  I have been rebuilding amplifiers and helping jukebox owners solve problems since 1967.  Jukebox Friday Night is your one-stop source for hard to find repair parts and service information!  Please note that the picture is a sample of one kit, yours will be different.
