Hi John;
I send you this link:http://www.geojohn.org/Radios/MyRadios/S120/S120.html
Have a nice day
Jules
Maybe someone can turn up a schematic for the 120A; but I don't hold out much hope. One characteristic of early Japanese-subcontracted consumer electronics is that documentation for it is exceedingly hard to find. There are probably exceptions to this, but I have yet to encounter them.

Thanks Jules. This should really help. John
I RED block marked up all of its problematic electrolytic caps also.

HALLICRAFTERS S-120A Solid State Communications Schematic:  |
:::Jules, the S-120A is an altogether different set from the S-120. The 120 is a tube set made in both the USA and Japan; the 120A is a transistor set made only in Japan. Who knows why Hallicrafters chose to keep the basic model number the same between these two profoundly different-technology sets: it causes a lot of confusion half a century later.

Thanks Edd, very readable now.
