bimo's comment is correct.
You should try screwing the BD139 to one output transistor or at least to the heatsink. Then listen to it.
I'm not sure which was the recommended bias for this amp model.

I think 50mA.

Hi Jhun,
Normally maylar/polyester film Caps the code printed is 0.1 means it's (100nf) like the one picture you have, 0.1nf is printed in code 101 or (100pf).

+/-42 is safe for AX11.If not please help because i have +/-42 power supply
Yes, it is safe.
Yes, it is safe.
Thanks Kandimba.

Yes you can NJW0281 / NJW0302
Can anyone guide with Fx100 Psu. I have 24-0-24 psu and 30-0-30 transformer. Is there any specific formula to calculate parts value.
Kindly answer. I have not been able to power up my amp because of psu.

Excuse me, the PCB of the APEX FX8 of Mr. SK kachhap is sold or available to all, since I searched for it but without success of finding it. Thank you in advance and sorry for breaking the issue.
I am in the process of building ax14 with Prasi PCB.
Due to space limit, only cap at hand that can fit into c4 c5 and c6 is 150uf/63v. Is there a problem using this value instead of 100uf and 22uf?

Hello chat72,
Yes, you can use.
However dont go by the lead spacing for C4/C5. You may slightly kink the leads and make 22 uf wth 2.5mm pitch fit. example attached.

Thank you Prasi, see if I can make them sing tonight.
