Addition of 1K resistor between pins 4 and 8 of National LM3909 IC in creases flash rate to about 3 times that obtainable when 300 μF is connected between pins 1 and 2. Modification of external connections gives choice of 3K, 6K, or 9K for internal RC resistors.- Linear Applications, Vol, 2, National Semiconductor, Santa Clara, CA, 1976, AN-154 ,p 2.
