Hello Gurpreet,
here is a rough b50 layout.

Thanks Prasi, Nice Layout. I will try on this PCB layout with Tip142/147 replace of BDW devices, because BDW are available in my local area.

Whatever pcb.... ask to Mr. prasi!
We are lucky that we have an expert!!!

Yes Thimios we are so lucky that we have an very helpful expert. Otherwise, if we ask to someone for any help then he flatly say No, As was happened to me but Prasi are always helpful.

Once again Thank You Mr. Prasi for PCB layout.

AX 14 Amplifier

Hi friends. I made the preamplifier for my new made Ax14 amplifier. Is there is need a tone control in front of the preamplifier?

 

[shabusf]

Apex A40, P30, TB3 put together

The beautiful Apex combo.. A40 power amp.. P30 preamp and TB3 tone control. HiFi sound.. Now playing on local test drivers.

There is a subwoofer processor board placed to take the sub pre-out, but not connected now.

The PSUs are from aliexpress.

A big thanks to APEX for the great designs. Alex MM for the error free layouts. And to all forum members whoever supported me either directly or indirectly

Is it good to use like this?
Signal from BJT Preamp to TB3 tone control then AX14 Amplifier.

Yes !! This is a good chain conection. But you should put the switche, if you want to do a bypass. If you want to take out the tone control TB3.
