[HomeBrew] Part Number Help

[Dennis Berry]

While cleaning out some junk box items, I found what is an obvious HV diode block, but I have no idea what the value is.  It is a Varo H402 7.  (There is a space between the H402 and 7 on the part.)

Does anyone have an old Varo data sheet that may tell what this is or can help out?

I'm sure I bought this during my 'must build an amp' days, but obviously never got around to that project.

Thanks for any help or ideas that may show up.
