You are listening to an great LVA/B30 from Lorenz made in Zuffenhausen near Stuttgart. The amplifier was build up with some parts from the "Deutsche-Wehrmacht" Not only the tubes, all parts are from the "Deutsche Wehrmacht". The tubes are: 2x EF12 2x RL12P35 1x EZ2 and LG12. The EZ2 is not original but there was a hole with no socket.

Great amplifier! I have the schematic diagram but i have two questions:
What is the value of the plate voltage of the final tubes?
What are the impedance values of the interstage transformer?
Thanks!

@MrCoccante the Anodevoltage is around 648V and the interstage is 1:1 from SE to PP. Two symmetric windings.

Sehr interessant. Das verstärker ist mono gegentakt oder stereo eintakt?
Ich habe eine EF12 auch, sehr gut pentod!

@Konstantin740iL Das ist Gegentakt Mono Gegentakt AB. Gab es auch mit 2x RV12P2000 statt den beiden EF12.
