Subject: Another AGC- and audio problem, help needed!

Hello ewerybody!

My video system here in Finland is PAL B/G, with Zenith SSAVI, random invert and decoded audio. I build canton 3 decoder, with Jens PALcodes. It works almost fine, but I have same kind of problem as few days ago messagechain by Charly. I think at i need AGC hack, on my videos.
My video is pansonic NV-HD 101EB with Mitsubishi IF ship model M52014SP.

Can anyone tell me which pins i should add the AGC hack capacitor(s) on it. I think it is pin number 13, original capacitor is 3.3uF. I try 47uf an 100uf, but nothing happens.
I can't find data sheet on internet, but i have schematic diagram on this video. The schemas includes a blockdiagram on schips operating principle. Same demodulator pack also founds on Panasonic model NV-HD100EB. I think at this model of videos are sold world wide different marks at least Grundig and so on.
I can send schematics anyone who can help me, by E-Mail.

I also buid a audio decoder with auto detection, as Kenny's design and plan add it on the videos. Does anybody knows what is the right place take the audio information on the decoder, direct on IF ships FM-Detector like pin 17, or on audio?? output pin 16, or somewhere else?
I don't own oscilloscope, so i try to measure carrier frequency by Metrix MX54 universal meter. This meter includes frequency meter up to 100kHz, but i can't measure any reasonable frequencies when the coding is active, so i don't know what is the right decoded subcarrier frequency.

I'm sorry my bad language.

Please help me.
