    Digital Piano Low Volume

    Sir ErMaro89 . . . . . Your referencing to j u mp er wire 17 does not show on any of the supplied references in this post . . . so it must be present only on a silk screen stamping on the PCB proper. So o o o o o o can you take this 94yo by the hand and his white cane and show him where it is...

    MOSFET IC for 3.3v Signal

    The circuit that Harald gave you puts out a normally . . . HIGH signal and pulls to ground . . . . LOW for an incoming pulse duration.. Unless changing the circuit for phase inversion . . . . . . that's the way it will be. But you found that a software change could correct for that, if...

    Meter screw up a fluke?

    I didn't elaborate in part, to see if someone would comment on the yellow component in the back that looks cracked. (...It's not) Spark gap cap . . . . avec . . . .PRECISIONLY sawed in gap.

    Digital Piano Low Volume

    Sir pianorep . . . . . OH tay ! . . .then . . . . consider this relevant analysis. You have a full 12 VDC supply voltage presence at the top lead of R1 and it then passes down to R2 which has its other lead end going to ground. Therefore the 12 VDC should divide in half due to there being...

    Tenma 21-7930

    Speaking of which, I can't seem to locate that PS in the schematic. The 324 and 339's will have to be getting their +12VDC power from a connection being common to the D1 cathode / C1 positive or hot side of R1/R3/R4/R5/R6/R7/R8/R9/R10/R11 or R12 because that all shared 12VDC buss, then...

    Sir RustyShackleford . . . . . Referring to the exising schematic, can you use it to fill me in on some parts so that I can mark up, YET another one, to be made. First forthgoing answer to you . . . is that the fifth wire of your soldering iron connector is made to the exposed external metal...

    Sir dkevin . . . . . I only NOW am seeing that you added onto your prior images co;;ection with your final photos. UNFORTUNATELY one thing that I will have to make a very educated guess at, is the bottom right corner where poor lighting coverage , depth of field of focus and that unwanted...

    Can’t find a 0.35 ohm 5% resistor anywhere

    You might also want to have a look (at) WHY the resi s tor burned. Refer to post 7's photo of HIS board and then . . . . . Look at the nearby . . . fractured outward . . . . case of a POWER FET and expect this burnt open part to be its source resistor, with the POWER FET being dead shorted...
