HELP on Gerber Files of M0YTH

 

re,
I had put a TDA2030 kit directly on my NJM2073 output, for me it worked fine, but the TDA2030 packed up and fried the NJM2073.
I know that we also need to add filters to the output of the TDA2030 to prevent runaway.

here my NJM2073 amplifier
?

Hi Gerard,

This looks interesting are you sharing the pcb files on github at all ?

Br Peter.
 

While you are at it, replace the audio preamp with the one designed by Wes. It is on his site

Peter,
I¡¯m not done yet
However, I did not receive an answer regarding the adaptation between NJM2073 and TDA2030.
It worked by connecting? (via flag inputamplier on a test model).?It¡¯s a bit like connecting an HP output to another amplifier.?See diagram
?You can use only le NJM2073 (ex for headphone) output or the combinaison of NJM2073 +TDA 2030 for more output power. (EX HP)
 

Ashhar,

I don't understood all?
What diagram?

on my sch¨¦matic, there is also a AGC.
?I don¡¯t know if we¡¯re talking about the same thing ?
There are also other additions to what I read on this forum
I¡¯ll provide the list when I¡¯m done
