Aleph 2 with 60V rails. - Page 3

AudioSan · 12:10 PM

it would work. if the signal transistors can take the voltage. another thing is. do you need that voltage? it's just a waist without bias that is equal high
(if it's not a very high impedance). and then you need more outputs. in other words. you got a aleph1.2

it would work , even without any change in circuit

I would increase few resistor values around small bjt in Aleph CCS , just for fun , but that will not influence operation in any way

ZM. yes, if bias is not raised

wich is useless not to do IF driving a 8ohm load

with bias at let say 4.2A, he may want some more outputs

thats 0.7A pr fet with 6 outputs. 70V*0.7A=49W dissipation pr fet. thats a little over my comfort zone for the fets

so what - he's obviously member of FAB
