still dealing with the buzz...and a very aggravating schematic...I've already found a few errors and outright circuit differences,and also found some evidence of work done on this radio in the past as well...i don't know which to trust,the schematic which at times disagrees with it's own parts list as to what is what or the physical radio that may or may not have been "fixed"at some point....
case in point c32 on the schematic...it links the center pin of the volume control to the19t8 1st audio amp[buzz gets louder if i touch this cap,but that may be normal]the schematic says it's a ".03",the parts list says it's .05uf paper cap and that's close enough to overlook i guess[i replaced a couple of those same caps in other area's...i didn't miss it,they're kinda big!]...the problem is that with the real life radio..this is a ceramic disc cap and if i'm decoding the color code right...it's a .003...now i would think a cap on the order of a factor of 10 times smaller there might cause some low freq cutoff.some sort of audio weirdness maybe...but frequency response has no issues,other than the slight buzz it sounds just fine...but it seems an audio coupling cap to me,which would lead me to think the schematic may be right...but would anyone care to give a better informed opinion than mine...which would be more the expected range of cap in this circuit?
