Kortek 19 inch CRT Chassis for arcade AC INPUT on KTN20
simondwilliams:
Hello,
I have a KORTEK KTN20 CRT Chassis I see AC input is 120 could you confirm if I need a isolation transformer ? Or could I connect directly AC 110 V on the two 120V leads ?
I blew the R601 5W 0.47ohm ceramic resistance on it and wondering if it because I plug the ac inputs the wrong way or because isolation transformer not present.

If isolation transformer is needed would you provide a good place and sku for one please ?
Thank you

120-128vac iso on these chassis
the other two wire that have been cut are 240vac for the degauss although if in the usa you can cross them them to the 120v pins
simondwilliams:
Ok I understand that I do need a Isolation transformer
For the degauss from what I understand it will not work is not crossed to the 120v leads ?
Thank you very much for your reply :)

yes the degauss will not function unless you link over the 120ac - so pin 1 to pin 3 and pin 2 to pin 4

and obviously replace the missing fuse
