VT40 Restore - Is my OT Bad?

[Micajah]

Rebuilding an early (71?) top mount VT40. I've attached a scematic. Replaced all the filter caps and a few drifted resistors. Brought up the voltage on my variac slowly and went to start measuring voltages and one of the resistors I replaced - V40 (it was burnt and not measuring anything) started getting hot so I turned it off. I checked all the Diodes and they seem to be good. After looking at the circuit I was wondering if the OT was shorted. It's a direct connect to the dropping resistor string of which VT40 (2 watt) is the last. The other 2-3K resistors are 5 watt.
Before I spend some good money on a replacement OT- I wanted to get some other opinions.
Using RG Keen's OT testing procedure with the OT still in the amp and Caps discharged. http://www.geofex.com/ampdbug/outtrans.htm
Primary side

"Noting which leads connect to the B+ line, measure the resistance from the B+ lead to each plate of the output tube(s). Plate windings are almost always in the tens to a few hundred ohms of resistance. A reading much over 1K is pretty sure sign that the winding is burned open."

Red to Blue - 151.1 Ohms - OK
Red to Brown 141.3 Ohms -OK

"measure the resistance of every lead to the chassis. This reading should be very high, hundreds of K or preferably megohms."

(here's where I think it's got a problem)
Red to Ground 28.32K
Blue to ground 28.48K
Brown to ground 28.47

From Primary to secondary

"Finally, test for the resistance from primary to secondary. A low value, under a few K indicates an internal short"

Red to Green secondary 28.41K
Red to Black Secondary 28.46K

I'm going to disconnect the Red B+ and the Blue and Brown Plate wires from the circuit and run these measurements again before I start spending but wanted to see what others thought.
