This is a question I am sure has been asked many times before and will many times again.

I am looking at caps to use/or buy

I have a batch of 0.1uF and 0.01 all at 400 Volts rating DC. These are typical met film caps

I also have some at 630 Volts DC in 0.1 and 0.22uF although these have shorter leads, non of these are rated for AC, OK so it is on a rectified HT set, but what about the line and frame time bases where it is driving scan coils or the LOPT, I guess I am concerned over nothing really even the yellow LCR caps are DC rated?

I think they are the same construction! as the ones sold by the BVWS although not the same case style, i.e. in that they are metallized polyester film. So would just appreciate a comment especially on the scan coil use.
