I have thrown away like 30 tubes in the last 5 years. I literally couldn't get people to take most of them for free. Unless it was a 100 percent burn free tested and working drop in for a G07 for free they just didn't want it.

No. Buy crap / broken / converted games on CL for monitors.![]()
Hit craigslist, picking up a 19" tv in an hour or so. Should work with an Electrohome G07 if I rewire the vertical yoke coils from parallel to serial.
How about a little more detail here.
I'm pretty sure this isn't how this works.
The difference in collecting, with regards to monitors
20 yrs ago - If you need another monitor, get one with less screen burn from another game, or even pay $200/shipped for a brand new one from Arcadeshop, etc. I never bought a new one, that seemed like way too much $.
Now - Either a) Learn to swap yokes and converge, using a thrift store TV tube; b) Find a direct swap TV tube for a k7000 or something; c) Use an old frame, a TV tube, and a universal chassis
Well, I think he means "series", and yes, not all yokes are wound that way (parallel vertical windings that you can easily separate and wire in series)- but if they are, it works fine (I have done it a few times now). You end up going from around 14 ohms to around 52 ohms vertical. Horizontal stays where it was and hopefully matches a G07 @ close to 2.2 ohms. If you use a yoke that has closer to 3 or 3.5 ohms it starts to have horizontal sizing and position problems that you may need to change a few components on the chassis to correct.
My view of it is that the yoke coils represent an output device to an electronic circuit designed to provide a voltage/current signal to a known load to generate a very precise changing magnetic field.
By changing the electrical characteristics of the coil, you may be producing more or less load on the output circuitry or creating a field outside of the intended range. It seems like this could lead to linearity and size issues or potential overheating in the circuitry.
I suppose, in the end, that the proof is in the pudding.
Practical results appear to trump engineering theory here.
If it works, it works, right? I just wouldn't think that you can change the coil parameters very much without running into the issues I mentioned above.
I'm in a similar situation with my converted neogeo.. hoping to find one with a 25 or 26" crt to swap over lol until that point, I'm usung a lcd temporary
I keep 2 pristine monitors in my closet in case of emergency...
Can we haggle on a price for one?
(couldn't resist)
I'll happily haggle with anyone...but when the lying/cheating starts...different ballgame.
Others just have more tolerance for that than I do.
I may be getting old and crotchety.
Get off my lawn!
