Default BY409 Diode - other p/n?

Looking to grab a couple of these diodes,

11.5kv EHT soft-recovery rectifier diode. - old part i assume as it cant be obtained from the usual outlets.

is there an equivalent? or a source for NOS?

There is a listing on eBay for a new item, but it purely lists the part number, and no other info so im a bit reluctant.

Thanks!

2CL73 is a 12kV rated, average forward current 5mA type from the 2CL69-75 EHT rectifier series intended for use with HF PSUs. This series is widely available but, as I believe that they were US-originated, they're not as familiar here as Pro-Electron coded types from the likes of Philips.
