The calculations are simple so you should do them since you want to change the project.

Hi!
If I use 3 2N5886 at the output, will Q2(BD139) and U2(MC34071) survive? There is any circuit change to be made?
Thanks! -
The TL081 opamp used for U2 in the original project has a problem called "Opamp Phase Inversion". If its input went too close to its negative power supply voltage (within about 3V) then its output suddenly goes high.
The new opamps do not have the phase inversion problem so Q1 is not needed.
Audioguru, thank you for your prompt response. I -

Hi Erivan!
It's the meter proposed in the main page of the project, but in DIP version.

Check the page of the author of the LCD meter:

Ok, Bugmenot. Thank you. This is one of the eschematics that I was looking. Good to know that you have build it. Didn -
Here the pictures of my original project and the LCD module... After I post inside pictures of it ok?
Hi everyone!
Bugmenot, could you please post some information about the LCD meter that you cited?
