Hello ALL
I have a JVFAX interfax, the basic one with the 741 OP amp installed.
Looking at the circuit, one imput of the op amp is tied to ground and the
other one is the AF input.
My PC has one rail tied to +5v and and the spkr output drives low.
WHat is the best way to decouple this ??. WIth Caps, for sure (I think).
Any help would be appreciated. Last time I tried this, I didn't know the
speaker was connected to +5v, you should have seen the smoke !!!!
