Hi everyone,
Building the Aleph2 J from the attached schematic, i got a question about front end component values. Since my speakers have 3 low points of 3 Ohms and a max of 8 Ohms, i like to match the amp to this impedance.
Using the excel sheet, turned out a rail voltage of about 37V is fine with bias of around 0,67A the power output should be like 140W at 4Ohms. The rig runs a little slower, wont need that much power and produces less heat (i hope
the junction temp was fine too. (according excell sheet around 100-110C)
Do i have to change any values of components in the front end to compensate for this lower voltage rails? When yes, which parts?
(see schematic)
Thanks a bunch!
ps im designing the PCB's they are almost done and i might have a few spares if anyone is interested?
