Use a 10k resistor between the pot pin(the one that is not connected to 5v) and pin 3 of the LTC1799.

It seems he put a new speaker in it as well! This is now the coolest dmg in the entire world.

I said screw it and reconnected everything in my dmg the way i had it. just cant turn it too fast...it cuts out then.

I have no idea how to picture this. The thread was posted in Nintendo Handhels, so I' assume' you are working with a gameboy, correct?

What do you have wired up? Is the LCT powered, did you remove the internal clock, did you wire up the LTC to the gamboy yet? Did you read the datasheet? I swear, you make it sound like you are just soldering the potentiometer to random screens in your house. tongue
Anyhow, the gameboy cannot handle nearly half of the frequencies that the LTC can produce, so what have you done with pin 4 on the LTC chip?
