VTA 120 hum then high voltage at one pin

So the other night listening to music on my wonderful VTA 120. I hear a couple of loud crackles and then a loud buzz, independent of the volume control and the whole preamp. I unplugged. I had a spare set of Electro harmonix Power tubes and I got a new rectifier.
I turned down all the pots. I installed everything and started to turn up the voltage. The lower left port pegged my meter immediately. Everything else was dead on. I shut it off. I get no resistance on the lower left pin.

Check the cathode resistor , if a tube shorts it may blow the resistor.
Pin 8 of the output tube is tigether with the bias test outlet connected to one
end of the resistor, the other end is ground. If no connection here the resistor is blown.
