I have the THS 4032 for some time but having difficulty due to it is SOIC.
2 days ago I decided to get it done, and found that if I pull the pin slowly, and fit under(below) the typical DIP socket, the pin 2,3 6, and 7 cud just reach the DIP pins.
So I solder those pins directly, and solder pins 1,4 5 and 8 with a think single core cable.
Well, some adjustment the clear the pins length is needed as I plug this socket with SOIC op amp into another DIP socket to try the sound.
I find the THS 4032 to sound great, better ten 2134, 5532, 5534.

So here is my 2 cents...

SOIC to DIP step by step photo1

Flatten the pin of the SOIC and place it below the socket. Wathc for the correct pins orientation... I did it wrong way the first time, being too excited and careless..!

Convert to DIP step 2

As we will place the SOIC just to rest below the DIP socket, Pin 2,3,6,and 7 have to be pointing up a bit so that the SOIC body is deeper into the body of the DIP socket. Place the SOIC on a table top and press the Pins 2,3,6,7 down till it is at the table level...

Soldering the pins carefully

I fixed the DIP socket using the masking tape on a table top. Place a small piece of masking tape to cover the centre sq hole of the socket so that the SOIC will stay flat. Solder one of the pin 2, 3, 6, or 7 first, then do the fine tuning adjustment while soldering another pin out of the pin 2, 3, 6, or 7. Preferably the opposite side. For example, if we solder pin 2 first, then next solder pin 6. Adjust the position of teh SOIC by fine tuning the soldering of this 2 pins. When it is doen nicely, the rest will fit nicely....
Pin 1, 4, 5, and 8 need to solder a thin cable to connect to the socket... here how I did it in the photo.

Done and inspect

Ok, so all the pins are soldered. We need to check the soldering points quality. USe a meter to check for connectivity and if any short circuit between the nearby pins.

Check also if it could plug in to...

Well, I would plug the socket into another socket, then check by meter again all the contact points to make sure....!
When this is ok, we have a DIP op amp!

Do enjoy and tell me your story and if any one bother to compare if same op amp with SOIC will sound better then a DIP op amp.

SOIC soldering

Next I will try to solder SOIC into the PIN curcuit board, this will be fun and I am sure the sound will be better. I hope to compare the sound of SOIC vs DIP, but the only op amp I have on both formats are 2134 and 134, well, may be it's not worth trying!
