....Hooked up a 9v with the + to chassis and the - to the 3 pin of the 6T5 it closes the eye about 15% from full open and drops the station vol by 30%  also voltage goes from -2.8 to -9.2v with the battery....

Try it with the 6E5.  The 6T5, like the 6U5 takes ~ -22 volts to close.  The 6E5 only takes ~ -8 volts. Instead of hooking it directly to pin 3, hook it to a point under the chassis that goes to pin 3.

Still something is amiss, you should have much more AVC than what you're seeing.
