    Discharging capacitors

    Post by islanddave on Tue Jan 15, 2013 9:38 pm

    Hello,


    I would like to take a look inside the st-70 that I recently built. Nothing is wrong, but I just can't leave well enough alone. Should I be discharging any of the capacitors in the board, or most specifically the cap cap before venturing around on the inside of the amp?

    Thanks Dave

    definitely yes!! you can use any handy resistor, somewhere around 100 ohms works well for lower voltaqes, not more than 1K for higher voltages

    How exactly would I do this? My electrical experience can be summed up in the fact that I assembled the kit and that's it. I am green but would like to learn.

    Thanks

    using one or two clipleads (one on each end of the resistor), and power off on the unit, connect one end of resistor to chassis or power supply ground, the other lead to whichever capacitor you want to discharge.
