Trying to find some service info on this unit. The volume only works on two
settings, off at 0 and low for everything else. It is a push button volume
control. The output chip is working ok and all other functions seem to work.
There are two chips that I have been unable to identify, these are a PA2019A
and a PMJ001A.
Any info or links to service info would be very helpful

Thanks
