The only steel cased scope I ever knowingly owned was an RCA. It was so old they called it an oscillograph. I've seen the Philco and Sylvania versions of the 3" WWII military scopes that were crammed into tiny steel boxes. I wouldn't even use one for audio work. They sat on a shelf at TV shops for decades because no one would use them.   Heathkit used aluminum, because they could produce their cabinets in house with simpler machine tools. Just because you are ignorant doesn't change any facts. Heathkit also had to consider shipping costs, since hey sold to hobbyists and repair shops where their only advantage over other kit suppliers was maybe a dollar or two. Therefore, they were more compact and lighter than failed companies like EICO. My first scope was an EICO 460 that was given to me because the CRT filament winding was shorted to the core. It was twice as heavy as a similar Heathkit, and not as well designed.   Heathkit got into electronic kits after WWII when there were millions of pounds of military grade components being sold for pennies on the pound. New CRTs were well under a dollar, so the designed a scope from what they could get.   Their prior products included a small, single engine airplane and furniture kits. They also sold electric organ kits, based on commercial products where you coukld save 1/3 to 1/2 overt the retail price by assembling the kit. A far cry from Dick Smith in OZ.   Take your meds and stop acting like a six year old. You can be a decent guy at times, but every time someone brings up something that you don't know about, you go nuts.

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.

Those aren't rare, among engineers or real techs.   > > The CRT has a MuMetal shield.   > ** How do you know that ?   From the photos that I linked to.   > > I see a NE2 neon and a diode used in previous stages that could affect linearity, but I don't have a parts list. > ** The OP is clueless and posting contradictory, total nonsense. > So are you.   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.

vjp2.at@at.BioStrategist.dot.dot.com: Nov 06 06:31AM Why is it in DVD players the first thing to fail is always the screen and not the motor? Well, at tleast the screen shows stuff but all fuzz and stuff. THis has happened to me with maybe four portable DVD players in the past fifteen years. Whereas portable TVs always seem to die by losing audio. I had two pocket one inch BW LCD TVs that lasted two decades.

The 12BH7 could be bad. i checked every resistor, all check good. i checked the pots, all good. i checked the voltage to a and b terminals on the crt, close to whats listed on the schematic. whats makes this different than a bench scope is it has no internal trigger. it is only triggered externally by an inductive pick up. same for the vertical , another pick up. one problem is i dont know how to induce anything to get it do do something on the bench other than a dot. however, if i turn it on, you can see the dot dive bomb to the right, and then come back from right to center. seems to me that indicates the crt is working ok. i posted a video on youtube.   https://youtu.be/be-Nae-sIYQ   still , when hooked to an 8 cyl engine, i get a normal image from left to center. from center to right it appears to be collapsed or squished toward the center. where the pattern ends at the center, the line is fairly thick and intense, like a partial collapse of a cga crt.monitor. thanks for any input.

Because of being used around cars, it is likely to have fallen onto a hard surface once or twice.   2.

You need to track down a Behringer repair agent and see what they say. Saying "digital noise bursts on the outputs " makes no sense at all. Did you means high frequency bursts? Pretty normal for Class D stuff.     ..... Phil
