Bb627 Amp

[Stee]

SEE SCHEMATIC 🙂
need AB1 bias + fan cooler - ultra silent (PC)

 

[lineup]

yes, it will work

try to figure out how much current you should have in each stage
and determine resistor values

R = Voltage/Current

i will take value from this amp pa600

😕

 

[Stee]

?

😕 because have the same configuration
just one drive stage in current more

lineup can you optimize this circuit?

better bias 0, 63V

tested on skytec amp with fan
better biasing is 0,63V
