Sorry it isn't for your model, that searching came up with nothing. https://www.manualslib.com/manual/1366970/Behringer-Inuke-Nu6000dsp.html#manual |

My eyes water trying to read the details though .... FYI That amp sells here in Australia new for a tad over $800. Genuine 3000W per channel. The similar model I saw did over 4000W. Still basically a throw away product. ..... Phil |

But you can download the pdf and view that at 500%+ to give a pretty clear view. -- Jeff |

Heathkit used aluminum for most of their cabinets. The CRT has a MuMetal shield. Do you have a schematic and a real oscilloscope? http://www.rsp-italy.it/Electronics/Kits/_contents/Heathkit/Kits/Heathkit%20IO-20%20ignition%20analyzer.pdf I see a NE2 neon and a diode used in previous stages that could affect linearity, but I don't have a parts list. There is a pot off the Neon lap marked 'Right Adjust'. Fair Radio still has some unused 5UP1 CRTs https://fairradio.com/product/5up1/ There is currently another IO-20 on Ebay, less the probes. https://www.ebay.com/itm/174516063489 |

Sigh, you are the queen of posting nonsense. Look at the photos in the Ebay link that I posted and see inside the IO-20 for yourself. I've repaired a lot of Heathkit equipment, and most of it used aluminum, except for some stereo equipment. They sold wood cabinets to cover a bare steel chassis, or you could build them into custom cabinets. I built my first Heathkit about 55 years ago. I built dozens for myself, and others. I also used a Heathkit color bar generator to transmit a color station ID from a black and white TV station. I genlocked it to our master Sync Generator, then used the monochrome video keyer to add color to a B&W 35mm slide. The information was displayed on the AFRTS page of the US DOD website for about a decade, before they purged all the shared emails. The other links included a schematic for the OP and a source for a new CRT, if needed. A working scope is quite handy when repairing an ailing scope. |

Did you miss his U-tube ? Vid worth a million false words. ......... Phil |
