carlo | Re: Queen Triggered Wah Thank you Mark. The Queen has three 4558's, one LM324 and a bunch of 1N925's. It has an AC jack with two wires - one goes to a 1N925 and the other to the base, (i think), of a 2N5088. There are three (of the same) semiconductors that i have no clue about. They only have 'SCOTT' written on them. Here's a photo: I'm pretty comfortable with tube circuits, but quite green when it comes to this stuff. Following your advice, i see that pin 8 from each of the three 4558's are connected to eachother...also connected to pin 4 on the LM324. I haven't gotten past this point yet. Thanks for confirming the black/neg wire connection. I'll take a look at your article about building heavy duty battery snaps. The clamp that holds the battery is attached to the bottom plate cover so the connection tends to get stressed whenever the bottom plate is removed. I left a message with Otto at New Sensor asking for a schematic. He's always been very helpful. |
