You could measure the current of the 300B and know the voltage it is on ....
Silver night SE 300B is on the low side.... meaning Trafo has less current available and is - if remember well .... near the 300V anode one-
Why they keep this and or the schematics hidden..Send them an email and ask.
Silver night PP is on 385V.
The current running the 300b and the voltage it is on gives you the information which Eml 300B or other you can use safely without problems later. Cannot just interchange so your question is excellent
Open the inside take a few pics and let us see the inside,
Audion silver is made for the eye not reallly the ears.... so consider.
