Voltage drop AZ1 = AZ11 = RGN1064 rectifier tube

Hello,

Does anybody know how much the voltage drop of a AZ11 = AZ1 = RGN1064 rectifier tube is? I looked at many datasheets, but cannot find it - or is it in the curves that I should look? :eek:

I'ld like to use it in an schematic that uses 5U4, if Az1 loses less voltage it's no problem, otherwise my amp will be short of voltage!

Thanks!:D
 
Hello reaction,

Just found where to look now you gave me one 'solution'.

Voltage drop at 75 mA: 5U4=25V / AZ11=40V / GZ34=6V!!! The GZ32 drops a little less than the 5U4 and still some more than the GZ34...

I'm gonna go for the GZ34 as they have a good reputation (except for the Chinese, although my local tube-guru finds many Chinese tubes including these excellent...) and I have some new production JJ's and nos Siemens lying around. :D

Thanks for the help; it's been noted for future use that you like the GZ32!;)
