Why, am I not supposed to be getting 193 Volts there?

Also I'm finally getting some response out of the tuner, it seems that two of my 6AU6 sockets will need replacing unfortunately, but the good news is that the voltages on the 6AU6 Video IF tubes are spot on to what they are supposed to be, I'm just not getting a good connection between the tube and the socket because of the sockets being faulty, (the center grounding lug is busted off on both of them and the sound IF socket some how popped one of its retaining rivets loose) and so there's no reference to ground with them anymore.

So anyways I'm going to have to see if I can find a couple of phenolic wafer style 7 pin tube sockets to match up with the original sockets and install them in place of the broken/intermittent sockets.
