hi George-san and all

I think HV6-1 is equivalent to GI HVPR10-MX12.

I have measured forward voltages of these diode modules using a CVCC power supply with 100-mA current.

Assuming each of the diode in a string exhibits 0.7 V forward
voltage one can presume how many series diodes are in the module.

GI HVPR10-MX12 6.36 V: 9 diodes
EDHD 15k 10.67 V per a leg: 15 diodes x 2 (which I am using)
SEMITECH KV-PAC SDHD-15k 12.97 V per a leg: 18 diodes x 2
Toshiba S5166A (13 kV 500 mA) 14.0 V: 20 diodes

I think 10 x 1kV 1A diodes in series is OK as an alternative.
