No tone or preamp right now. Would be adding NE5532 based preamp soon. I shall upgrade it to P30 later

Pending work: Preamp, softstart, TB3 tone control

Thank to Mr. Apex, Alex MM, Prasi, Sumesh, Sunny, Bhushan, And everyone who have helped me either directly or indirectly.

TP2 preamp

 

[surjitsharmaph]

Does TP2 required TB1

Does TP2 required TB1

No it does not, TP2 is preamp with tone control. TB2 and TB3 is only tone controls.

 

[surjitsharmaph]

Does Tp2 has the bass like that of TB1 and TB3 combination with loudness on

Yes, TP2 use passive tone control circuit without NFB

P30 preamp, volume pot help

Hi Mr. Mile,
As per the P30 scheme volume pot is 100K. Is that a LOG or LIN pot?
Also, I do have a 10K LOG pot, shall I use it with P30 without any modifications to the scheme?

I have added NE5532 based preamp and TB3 to my A40, but the results were not satisfactory, sounds like the preamp degrades the audio. So I am planning to make P30.

Thank you.

Regards,
Sha

You can use 10K LOG pot with P30 without any modifications to the scheme.

TP2 one channel schematic without PSU.

tell me what might happen. The amplifier works. The sound in the speakers is, and the rest current is not regulated. In all positions of the regulator on resistors (0.22 Ohm) shows zero always
it is about ax-14. (circuit boards did himself)

Hello Sir Apex, I would like to build the AX11 amplifier. Can you re-publish the latest PCB version, diagram and list of amplifier components?
I found some options in the forum (BD249C / BD250C or 2sc5200 or 2sa1943) but I have some difficulty and choose the appropriate, I have little experience and this will be my first amplifier.

Thank you very much in advance.
