Since I REALLY do not want to wrap or unwrap anymore pins, could I plug my San/Bar FM tuner card in slot 3 and get MOH?
I was thinking slot 3 because now slot 4 is occupied by my 401A card.
Also, on the FM tuner card, there are 3 switches I don't understand. There's a SP/ON, AFC/ON, and EXT/ANT switch.
Don't know what to set to what etc?
Once again, you guys are the best!

Sure, you can do that. Just make sure pins 3 and 18 are connected to the line card's pins 3 and 18. As for the switches:
SP/ON controls the internal speaker so you can hear it while tuning in a station. This would normally be left off.
AFC/ON controls automatic frequency control to keep stations from "drifting".
EXT/ANT allows you to use the cards internal antenna or to connect an external one.

Well, I just tried it out. Couldn't hear anything. Pins 3/18 are connected to AG/AB respectively.
The meter is flicking up and down as if recieving something, but no radio on the other end.

There seems to be some kind of 500 ohm varistor on the back of the card. It looks like the problem was coming from there.

The smoke comes when I put a call on hold, and either pins 17 or 18 heat up big time. 18 is AB, 17 is BB.

You can't have 24 volts on pins 3/18! They are for music only. By having 24 volts on them, you may have fried the 4201 card.

I don't think I fried the card. So remove pins 3/18 from AG/AB respectively?

Yes, pin 3 from slot one goes to pin 3 of slot three. Pin 18 from slot one goes to pin 18 of slot three. That should be all you need to do.
