Radio shack stereo disco mixer

[Alpi]

Can anybody tell me where to find a schematic of this. It's an all
transistor one and the number is 32-1100b. But I think that the 320-1101A is
the same.
When I connect the battery, the voltage lowers to 2 V indicating a shortage.
But without a schematic it will difficult to find the problem.
Thanks

Check the problem with a ohm-meter. Suspect a electrolityc capacitor, a
diode or a stabilisation regulator in the powerpart first.

I have just found a problem. The mixer has a generator which delivers about
20 V DC build around a transistor C1815. This transistor was out. I could
replace it by another one coming from a junk. Now I can perfectly hear with
the headphone what is played. But I think one output channel is wrong. To be
solved tomorrow.
