Request Technics ST-C03 micro-series tuner service manual

i'm new to this site and love the idea of sharing old material as the one i'm asking for.
i have a SU-C04 ST-C03 RS-M02 SL-DL5 and a couple of SB-K915 all technics.
i'm also uploading each of the components owner's manual (except for the speakers), and also the schematic of the RS-M02. So i'll be glad if i can be of help to anyone.

pd: the reason i'm asking for the service manual of the ST-C03 is that i've found that after a few minutes of playing i can't change the radio or else i finish of with a scrambled display and some random frequency playing over the speakers
