    Piezo/Piezo to Piezo/Switch converter for Roland TD10 Drum module

    It is starting to make sense. I see I can measure the piezo output, so I compared it to the OEM drum, and also compared that to my circuit output for both head/rim (Tip/Ring respectively). I noticed the values were off, where the switch / rim was too high. The first thing I added was a diode...

    Piezo/Piezo to Piezo/Switch converter for Roland TD10 Drum module

    Good day, I had a need to run two separate piezo trigger cymbals into a TRS input that was expecting a piezo/switch signal. The Roland drum module was designed to work with a single drum pad where the head was the piezo and rim was the switch, so in order to use two separate cymbals that are...

    Identify SMD Capacitor

    Wonderful news! Roland parts was able to find a part number in a list even though they don't carry it. 25cv10bs Searching for that brings up two main choices: 25cv10bs - SANYO 25cv10bs(10uf25v) - SAN I don't know if that would be the same thing, and SAN is abbreviated. The operating temp I...

    Identify SMD Capacitor

    Thank you both. I questioned if the 08 was some indicator of tolerance or operating temperature...or if it was a multiplication factor of .01, but I thought that was only for pf. For convenience for others, the numbers displayed on the two caps are in three rows: 08 10 25v Would I be save in...

    Identify SMD Capacitor

    Good day, I am not an electronic engineer, but I am trying to fix my Roland TD10 drum module. I just got it used, and after three hours of playing, I smelled the typical leaky capacitor smell, and sure enough, about 5 minutes later, the kick drum started distorting. I let it cool down, and it...
