Question about Kenwood Audio Players & Recorders
First of all take an AA 1.5 cell and use it to test the speakers you are using. If there is good movement of the coils identical to both sides , we can proceed further. Now open the power amplifier and check within the output side where all the mosfets are mounted. Check for the +B( the main Voltage) in both the L&R sections of the amplifier. Now use a good signal tester or even you can use a line output audio with a serious capacitor ( about 2.2 mf) to check stages in ascending order from the output stages. Test at all the couplings to confirm the gain of the amplifier. The fault could be failure in the preamplifier or the source selector. Try to check all the inputs , if there is better output in any other source input, in such a case use this till you can get help to change the preamp selector. hope this helps. Good day
