Thank you Barry, but I've searched the whole EDAboard forum. No schematics for the KT-30 tuner appear as results.
Google Search also does not produce any result for the schematic.
I don't know what more can I check?
Well, you're partly right. Google produces lots of useless results, but none of them can offer a PDF or a JPG with the schematic, which I am asking for.
