NS-2 Minus Loop and on/off switch question

First of all forgive my english as english is not my first language.

I have a M5207L01 IC chip and I am thinking of building a stripped down version of an NS-2 because, for my needs, I am thinking of not adding either an on/off switch (as it's going to be always on in a loop) and the send/return part of the schematic.

I think I figured out what to do about the switch but I am not too sure about what to ignore on the schematic with regards to the send/return part.

I am by far not an expert so before I start breadboarding the circuit (and start the trial and error process) I was wondering if any of you (who knows tons more than I do) can suggest me which parts of the schematic I should ignore without compromising the functionality of the circuit.

Thank you in advance for you help and patiance

Omit Q2, Q4, Q5, Q6, Q7, Q8, Q11, Q12, C6 and their relevant ciurcuitry..
Short Q1 Emitter to C9 and C26 to Q3 Base..

P.S.
Just a rough estimation after a slight circuit view.. :icon_wink:

+1 what Antonis said, except moreso!

All the FETs related to switching signals can go, and that then makes a large number of biasing resistors and DC-blocking caps around them redundant too. Plus if there's no FET switching, you don't need any of the components related to switching those FETs - that's broadly speaking everything that's connected to the Gates of Q5, Q6 and Q7.

There's a lot that can go, in short.

I can't thank you enough both of you

Thanks, but Antonis has done the hard work here! I wondered what the circuit would look like with all those pieces taken out but I didn't sit down and do it, so many thanks to him for that.
