Browse the content of the threads in new Window  Thread: Melq 6e5p driver stage for ss? in Melquiades Amplifier  29 Replies 
It is not to mention that 6n1p is not very good sounding tube… It is interesting that you have built Zaratustra with gas driven 6e5p. I do not feel that it is “most powerful fully pure class A amp in existence”. Power is power and it is defiled th...

[quote user="anthony"] Firstly, the -200V Bias supply takes ages to come up to voltage but it does get there...no issues for the +200V side, it charges is 200uF caps almost instantly, but 9,000uF on the negative side takes almost 90 seconds to ge...
