Replacements for tube style monitor flybacks...

Have the transformer wound to your specifications:

Is it (are they) WG monitors? I would assume there is aftermarket support for these as they were *so* common.

Electrohome monitors.

It's the aftermarket that looks like it is stopping production of all flybacks...

Few years ago I did see a lot of old model TV HV transformers on ebay. Maybe you can even get an old color CRT based set?

But LCDs (or OLEDs??) is likely the way to go. Some OLEDs may suffer from burn in.

Ultimate alternative is a projector?

It is somtimes possible to rewind line output transformers. I have done it, although it wasn't the easiest of jobs.

Yeah, another project to add to the list!

I need to get into another business where we don't have to reinvent buggy whips regularly - but it is fun (sometimes)!

John :-#)#

Good points - there are some transformers that can put out the HV needed, and then add some more windings to get the others...

The problem is will people pay for a new flyback that costs upwards of $200 when they were previously under $50? If I have a few thousand $$ to spare I could get 100 to 1000 made, and that may be the route to go.

Canada?

If you are doing this to maintain machines on a route, then a fix may just be to pick up scrap arcade pieces and part them out.

If you are doing this to cater to "home sales", then LCD upgrades may be a better route (as they likely won't s*it the bed and need future servicing)

Mechanical/cosmetic issues would then dominate.

These were the best of the 19" monitors and were used extensively by all US arcade manufacturers. Wells Gardner seemed to be the 2nd choice monitor and then others when they couldn't order enough of those two.

Nah, this is for collectors and home owners.

Yes, LCDs will work if you can find any 4:3s any more! They are getting expensive...

I like the curvature of the original tube screen over the flat LDC style. As do many collectors.

The latter is unlikely to work since those flybacks also generate the horizontal deflection, plus helper voltages, plus, plus. You'd also have to replicate all that, separately, and then this whole project can turn into an expensive and time-consuming can of worms.

IMHO finding the flyback transformer or a used monitor you can scavenge it from is the only viable option.

I only recall using EH for vectorscan monitors. They made one that was fast enough that you could actually emulate a raster! (but noisey as hell when you were hammering on the deflection amplifiers)

Then money is less of an object.

You could always make a bezel that crops the displayed area.

The depth is the real win. On my ToDo list is to build a cocktail with a large LCD panel; a regular CRT would make it a piece of furniture instead of a table (that could be used as such).

Or, a large attache case that opens to reveal the monitor.

I've been shedding arcade pieces simply because of their "bulk". I could rationalize a dining room table with a game built in much easier than an upright cabinet! (or even a cocktail with no room for your legs)

Which Chassis, motorola?

I stock a couple for the old Space Invaders Chassis with BW CRT, 19 in similar but yea its like 5KV out, not 30.

How much of that $50 is your time to diagnose the problem and replace the part. In other words what is the percentage impact on the repair price? CRT becoming more expensive maintain; I'm sure everyone knows that, and if they want to stay with CRT, they will be prepared to pay for the privilege.

That plus there are GPU shaders that can emulate scanlines, color bleed, and other CRT artifacts pretty well, run the video output through some post-processing for that "tube" feel..

Eric the LCD! “I picked him out of thousands. I didn’t like the others, they were all too flat.“ (Apologies to John Cleese.)

That would be a monumental task -- taking existing video, digitizing it, post processing in a GPU and then redisplaying. Video games (arcade pieces) were "fitted" to their component parts. You didn't buy a generic multisync monitor and use it in one of its "modes". Rather, you designed the hardware to drive the monitor AT it's specified extents. (Doing otherwise would be wasteful).

Quantities weren't particularly high (10-20K total production) but the industry didn't have room for slop/margin. A game *might* have to pay for itself in as little as 90 days (the "90 day wonders" where the market moved on a few months after their release)

John seems to be addressing the folks who either want a "home arcade" (for its novelty) or want to preserve a particular machine (sentimentality) Mame just doesn't cut it on either score.
