    TDA1554 Two Channel Audio Amp Chip

    Hi Mukhalled, If you do not attempt to use the four-channel configuration you could take a look at TDA1552, TDA1557 or TDA 1558 instead. These are all 2 X 22W. Perhaps you can get one of these in the electronics shop. I hope this helps. ;D

    AC/DC adaptors: voltage over normal?

    No Kevin, I did not say it was the maximum current just the nominal. Nominal and maximum is not the same. But I said that the transformer should not be overloaded, and it will be if you double the nominal current output, which was autirs question. To complete the answer to autirs question; yes...

    Maybe you need to change the ball to make it work. A trackball has a hard surface ball but the standard mouse has a rubberball or at least a rubber surface ball. There is no easy way to suspend any

    OK Mike, The potentiometer : 64-210-36 For C1 you can use this: 65-230-05 C2 is OK. For D1 use any red LED. D2 is correct, so is Q1 and Q2. IC1 is here: 73-043-63 For T1 you can use this: 56-180-38 SW1 is any single pole switch you like, for example: 35-305-16 It
