G07CB0 monitor question....isolation transformer?

[Shift21]

hey guys I got a G07CB0 that I got from a friend, founf out it just had a blown fuse, I have two k4900's that I know require the isolation transformer to run, does the g07CB0 need the same or can it direct link to the 120V power supply?

any help would be great and thanks.

You should be able to use the same ISO.

If you're not sure, NEVER hook a monitor directly up to 120V.

the only monitors that can run without isolation transformers are those with switchmode power supplies (evidenced by a mosfet switcher tagged to a close by "big yellow transformer".) these monitors will also be produced sometime in the 90's.

as so:

those which use a regulator to create the power supply (evidenced by a big multi legged transistor looking beast) need isolation or they blow up. these types of monitors were popular in the early 90's and before.

as so:

or possibly as so:

Electrohome G07 monitors REQUIRE the use of an isolation transformer.

This tag should be attached to the monitor's power cord:

all monitors will operate just fine on an isolation transformer whether it needs it or not.

not all will run without isolation. better safe than sorry.
