    Distortion Pedal Redux

    Hello, @Audioguru , film capacitors do exist in 100 pF. The polystyrene capacitor is an example. In the old days they where called Styroflex capacitors. They are often used when high temperature stalility is needed...

    LED resistor value/voltage doesn't make sense

    Hello, Yes, you will need to measure the voltage accross the led. This tool might help to get the resistor calculated: https://www.allaboutcircuits.com/tools/led-resistor-calculator/ Bertus

    LED resistor value/voltage doesn't make sense

    Hello, The voltage will only be lowered when a led is connected. Measuring the voltage on an open connector will give the 5 Volts. It depend a bit on the input resistance of the meter. A digital meter is usualy about 10 MegaOhms. An analog meter is given in KiloOhms per volt. The newer led...

    what is AC dual 24V?

    Hello, The amplifier need a dual powersupply. As the expected power input is 24 Volts AC, there will be about 33 Volts on the amplifier. When you use one 12 volts battery for the plus side and one for the minus side, the power will be much less than the maximum power. Bertus

    I'm Back- sort of

    Hello, The 1N914 and 1N4148 are almost the same. Here are two datasheets that will share info on both diodes. As for the led, the forward voltage will depend on the color of the led. Bertus

    Datasheet or Databook Wanted

    Hello, No info can be found besides the following page: http://www.seekic.com/newstock/RH7600-3A,RH7600RA-2,RH7601RA-1.html It is likely an OEM product, from wich only the manufacturer has the data. Bertus
