Hello, I write to You to consult about two tuners, I am doing a video decoder and
I got myself two tuners of old vcrs,also I tried to get the diagrams of these vcrs but I didn't find them here in Mty Mex, then I wondered if some of
you know the configuration of the pins of these tuners, the videos both are
similar for 110 channels uhf and cable the models of the videos are Toyomenka
model TMK 4200VHQ inside the tuner uses the LA7530N IF C.I. and Dynatech model VR-20 inside uses the AN5135NK IF C.I., the vcrs are old that had input for uhf of 300 ohms, and vhf of 75 ohms.Well I hope that You can help me.I post the drawings of the tuners in the next address:
