I have two 2570s that kept blowing the 2 amp fuse, replaced some diodes and I think they may work. The only thing I am having a problem with is that I need a monitor to test them. Does anyone know what I can use. I have a 2574, 2575, 2775, 2792 sitting in my shop. I tried the 2574 but I got no picture. I hear them turn on but thats it. I'm afraid to leave it on for a long period of time, I don't want it to cause any damage. I must also add that I do not have a yoke for this model.

I'm having some trouble here - which is the 2500 series?

It sounds like you're describing a standard resolution 25" K7000 series (25K7191, 25K7101) which requires operation from an isolation transformer.
The other models you mention are:
25K7400 (25", standard resolution, no isolation needed)
25K7500 (25", medium resolution, no isolation needed)
27K7500 (27", medium resolution, no isolation needed)
27D9200 (27", digital, multi-resolution, no isolation needed)
What model does not have a yoke? Many monitors cannot power up with the yoke not connected.
Are you trying to test all these monitors? If so you need to provide power (isolation transformer is prefered even for testing the non-isolated models) and a video source such as from a monitor pattern generator.

Well, I have yokes and tubes for those models listed 7400s, 7500s & D9200. I just don't have a tube nor yoke for these chassis that I have for repair (25K7197 & WGM2570).
