My Apex AX6
Hi Mr. Mile
This My Project not yet finish, I had trouble getting Transistor final 2N3773.
if i replace it with 2N3055, what other component must be replace?
Thanks.

You can use 2N3055 with 60V DC rail maximum and without changes.

i can't find transistor 911, what alternative part to replace it?
Simple regulated psu for AX6
Thanks Mooly,
That got it working but it doesn't run right. Gain is very high. 0.5V on the input makes the negative wave clip. And right, bias is very low. Looks like Mile added a vbe multiplier to AX8. Maybe that is the one to build. I wonder if there is a layout for that one.

The gain is approximately equal to 1+(R18/R16) which is 45. Simulation bears that out with 64.4mv rms needed to obtain 2.86 volts output which is a gain of 44.5. The small discrepancy can be accounted for by the very small attenuation caused by R1 and the bias network.
The bias is easy to fiddle in simulation, just increase R11 to around 80+ ohms.

Here is a spice file for the AX8. It works OK but clips kind of ugly and it also has pretty high gain. THD .02.
