Replacement PT question

I have a Knight KN-728B that needs the power transformer replaced.

The original PT is: 640VCT 130ma
6.3VCT 5.5a

All I can find are a couple of Edcor's that are close but not exact.

- 600VCT 200ma
6.3VCT 6a

and

- 660VCT 200ma
6.3VCT 6a

Can I use either of these?

Thanks
