My modified SURF MASTER PRO kit

Nice... but what is the modification? The PCB size?

Its dimensions have not changed, only the NE5534 IC amplifier has changed

Hmmm,

Why did you do that? The LF357 is no longer manufactured and is very difficult to find genuine ones... unless you are satisfied with fake LF357 from China.

Yes, dear friend, it is the original LF357, bought from China, it is an old production,
I did not have access to the NE5534 IC, and the original could not be found in our country, so I used the LF357 IC with changes in the PCB.
