HP-67 Card Reader became very touchy

[Alevin]

May be in my previous post 1st paragraph I induced missunderstanding.

I am not the OP on the thread, but another else guy, and I have not yet changed any cap in my HP-67 ( I suffer of this syndrom in, both Hp-67 and Hp-97). Indeed my very first question is about the location of this power line capacitor in the HP-67, and still is open.

In any case, thanks Tony for your kind and detailed replay about Hp-97, that will be useful when going to solve the HP-97 problems, after picking up the ones in HP-67
