Flyback for Wg k700

[juanchocnva]

Hello forum 

Ok so  am ready to replace the flyback of my neo geo cab the picture its now very blurry and the colors tear when trying to adjust the brightness on the flyback
the chasis needs cap kit and flyback replacement since all the cap look pretty old and i want to keep this monitor running for some more years   


so my problem is that most of the wg k700 use a flyback with only one anode cable going to the tube but my has two one going from the flyback to the tube and the other one from this thing to the tube
so my question is if i order the regular k700 series kit from bobroberts would this flayback replace my old one or i need one with two anode cables??

  am a noob at this but everytime a watch a video on youtube on how to replace a k700 flyback they always have this single cable flyback
and what is that thing in they flyback any way?

Your picture shows you have a Zenith made K7000A. The flyback for that model is completely different and no longer available anywhere.

You need to install new capacitors first anyway before doing anything else.

thanks alot for your response :


 
am a guy with bad luck

yeah am doing the cap kit but since am doing in i really would like to install that new flyback
so would you recommend me buying a new chasis?

what are my options

never mind

just quoting from other post

info on the zenith K7000A chassis as provided by Ken Layton:


Around 1990 or so Wells-Gardner was getting so many orders from game manufacturers that they were falling behind in production. The k7000 was their most popular model at the time for arcade video games. So they subcontracted with Zenith Electronics for Zenith to build the k7000 MAIN circuit board and NECK board (but not the remote adjustment board). This became known as the "K7000A" chassis. It did not have the usual "P447" or "P538" numbers silk screened on the circuit board like the genuine Wells-Gardners did. Instead the main board is silk screened 204-2205-07 and the neckboard is silk screened 204-2203-02.

The easiest way to identify this version is that there are TWO PINK wires going to the suction cup whereas the standard Wells-Gardner k7000 has ONE RED wire going to the suction cup. It is unfortunate that Zenith chose to partly redesign the circuit board from Wells-Gardner's design in order to use a proprietary Zenith made flyback. This particular flyback (Zenith numbers 95-4149 and A-15945) is no longer available anywhere thus making this chassis unrepairable should the flyback fail (a common problem). The flyback for standard Wells made k7000 (the 0528 flyback available from many suppliers) will not physically nor electrically work to repair the Zenith made chassis.

So if you have a k7000A chassis and the flyback is bad, then you're only hope to repair the monitor would be to either get a working regular k7000 Wells-made chassis (direct plug 'n play swap) or order an 8liners.com universal replacement chassis.

BTW, the k7000A uses the same cap kits as the regular Wells-Gardner K7000 monitors. Zenith kept the same component designations (and values) on the pc boards at least.

Oh, and to further confuse people, Wells used (mostly) Zenith picture tubes in both versions.

what would be a good chasis to purchase ??

a real k700 series?
where should i be searching for it ebay?
how much is a good price to buy it  working and not working?

thanks for your response
