Ok Back together.. Seems to work Well a Little bit.. It will Osc and put out frequencies.. Quite Stable

But When I turn the Sensitivity control all the way Clockwise I can only get it to Read Grid current About 1/2 way Between pegged to left and 0..

Voltages measured..

115 DC after Rectifier
110 DC After 1K ohm resistor

Pin1 of tube 81 Volts DC
Pin 2 of tube -15 Volts

Any clue why almost no grid current on meter??
