Isolation transformer

[chris79]

If your installing a new monitor that does not require an isolation transformer in an arcade cabinet where the previous monitor needed an isolation transformer.  Do you have to remove the isolation transformer?

[shardian]

You don't really have to remove it from the cab. You can just disconnect it from the live wiring.

you can still use it if the voltage is correct

[chris79]

ok i'm thinking about replacing my electrohome g07 with maybe a wells gardner k7700 in my galaga cabinet I'm just hoping there isn't any problems with leaving the transformer hooked up but if there's a risk maybe it would be best to unhook it

[grantspain]

it would be like removing an extra piece of protection and i thought the wg7000 series need an iso tranformer

[chris79]

there K7700 and K7200 do not need a transformer but there K7000 do I wouldn't think there be any harm leaving it there the monitor i'm putting is the same size and specifications

i can't see how you could damage the monitor but if you want to be 100% sure drop ken layton a pm,he's the expert on wg

ok thanks for input

Absolutely not!  Feel free to leave the iso in the cabinet.  Though your new monitor doesn't require it, there may be a time in the future that you'll need the isolation.  It'll be there if you do.

Let me put it another way: using an iso transformer on a monitor that doesn't require it won't hurt the monitor in the slightest, but the other way around will kill your monitor.  Use it with no worries.

thanks I figured that I just wanted to confirm it I guess newer monitors have the isolation transformer built into the chassis I guess

Hold on thar! You're replacing an Electrohome 19" horizontal (shelf) mount monitor with a Wells-Gardner 9" horizontal (shelf) mount monitor?

The 7700 is a 9" horizontal (k7000) and it requires an isolation transformer.

[chris79]

sorry I had the wrong number it's a D7700

here is the model number WGE1977-H0GS39R

[Ken Layton]

And after reading about all the trouble with Wells-Gardner monitors (especially the "digital" ones), you're still going to buy one?

[chris79]

well I have not made up my mind. I am thinking of buying a Vision Pro Monitor Mikes arcade sells one with a cocktail mounting frame.  I posted a topic asking if Vision Pro monitors are any good. 

I take it all of Wells gardner new monitors are equally as bad?
i'm seriously considering Vision Pro now I just hope there not bad.

I appreciate your time if you have any advice or suggestions i'm open to them.

thank you Chris
