Sorta newbie 38-690 low volume
#30

This is what I was trying to make you check. Icon_smile When I ask to pull the 6K7 Bass amp. 

But surest way to make sure the base is working is do what I did, de-solder the high path. It is very easy, the very first photo I posted here when asking you about that wire earlier shows it, but let me edit it to circle the parts.

   

The resistor and cap whose leads twisted together is the Hi-f path; the lead that has to be desoldered comes to a nice large solder post on the left (photo does not show it, it is under a wire), also circled red. Disregard the arrow - it is from the previous edit.
When you desolder it you will only have the bass left. See if it is there and if it is enough when the antenna is connected.
Mine was not that loud but I guess this is what it should be.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
