Something's fishy. If it's the focus rectifier (1V2 or 2AV2, I think you can swap those, but the filament voltage is 1.1 on the 1V2, vs. 2 volts on the latter. Being a simple diode, it has no bearing on the focus voltage.

Please be kind to you flyback! Measure that high voltage, and set it at 21KV or whatever the manual says. The biggest risk is overburdening and burning out the flyback! I've seen more 60s color TV flybacks killed by misadjusted high voltage than any other failure cause.

If the focus voltage (or high voltage) is low, so probably is the B+ throughout the chassis, and you need to troubleshoot and find the cause (leaky filter cap, horizontal problem, etc etc).
