Mike A:
I have been testing my inventory of CRTs the last few days and I thought this was relevent to the thread. I picked up a k4625 CRT awhile ago. I was buying a different game and I saw that CRT in a cab in his garage. He said he was building a multicab but the monitor died when he plugged it in. He told me I could have it for 50 bucks. It turns out he didn't have an isolation transformer in the cab. I tried to help him out, but he just wanted to be rid of it. Luckily it seems like the only damage was a blown fuse. With a new fuse and the proper isolation transformer it has run beautifully for hours. That pic was taken before I mounted the fuse holder to the chassis.

Nice score Mike - we should be glad that there are plenty of dudes out there that don't understand the importance of ISOs. How else would we get dirt-cheap prices on great cabs? Mind you, lucky it was just the fuse that blew (guess that's what it is for).

so today, i replaced the parts my friend told me, i decide to give it a chance, hooked the monitor and voala, it turns on just fine, but to be honest, i dont want to risk it, im a find an iso and use it as it should, ill keep updating this.
Zebidee:
Technically you can run an arcade monitor without an ISO if it has a bridge rectifier circuit (that Wei-ya we were talking about before has one, it is that row of 4 diodes near the big fuses), but it is always better/safer using an ISO regardless. In my case I have to step-down from 240v anyway so it really is a no-brainer to get one transformer that does both.
When I bought that Wei-ya chassis I asked the seller (company)
Q: "Does it require an isolation transformer?"
A: "Yes".
