This is a premium rebuild kit for the Wurlitzer jukebox model 526 tube type amplifier found in the 1600A and 1650A. It contains all brand new first quality capacitors and a schematic diagram of the amp. Each cap is hand-numbered to aid in identification. Replacing the caps in an amp will usually greatly improve sound quality and reliability. Please note that the picture is a sample of the kit, yours may be different. The size, shape and color of the capacitors will vary. TUBE KITS are available for this kit, or any jukebox amplifier, inquire. I have been rebuilding jukebox amplifiers and helping jukebox owners solve problems since 1967. Jukebox Friday Night is your one-stop source for quality repair parts and fast service!
