Default Ned help to install thermistor in chip amp

Hi!
I am finishing my dual mono 3886 chip amp.
In the picture :
A shows how I installed the thermistors, just to test the amp, without switch.
Four thermisthors in the four wires of secondaries.
In the final installation, the boards, psu and transformers are in a single box, (I hope I'll have not noise...). I will use a single IEC plug for both transformers.
- Should I connect as 1? , (one thermistor in positive pole, between power chord and switch)
- Should I connect as 2? , (one thermisthor in neg pole, another in pos pole, between power chord and switch)
- Should I connect as 3? , (one thermisthor in neg pole and a switch in the pos pole)
My guess is 1 is right, but I'm not sure...

I hope the drawing is clear.
Thank you very much!!!!

I do not think that a thermistor should be placed in the neutral line.

I think you meant HOT and NEUTRAL for the AC! and NEGATIVE/POSITIVE for DC voltages

You can use one in the hot line or use one in hot and one in the neutral line! I have mine like in #1

Hi!
Ok, I will use 1. The simpliest.
Thanks to lanchile and DUG.
I will make a post for this amp. It was my first DIY project but I think I took it to the maximum performance that a chip amp can achieve - with a good help of a diy member...
