TB-303 power supply

[Ken Stone]

Point 1 - you have no earth connection on the 78M12 (from the center
pin)
Point 2 - regulators such as 78M12 REDUCE the voltage. They must have at
least 2 to 3 volts MORE than their specified output voltage fed into
them. You would need to run what you have drawn off 15 volts not 9 volts

Point 3 - please don't mail binaries to the list.
