Elektor Formant Modular

i wanted to say hi and express my relief in finding this group.

i thought i would jump in with a question. ive accumulated a few formant modules and ordered a power supply for them (from curetronics). i noticed that some of the modules have a 31 pin connnector on the back of the card, whereas some of the (older?) modules only have a few pins attached to the back.

im thinking to do away with these connectors, and just solder to the proper pins to power the module / connect it others.  does anyone else have experience with or opinions on this?

thanks
