Thanks for the help in the "items wanted" section on the Sony HV block for this set.

It looks like the HV block in a Sony KV6000 is similar to the one in the KV9000. Looking at the circuit, it seems to supply the H-STAT voltage from a potential divider across the entire EHT.

It might be possible to make up such a divider for my set. Sadly none of the circuits give the values for the resistors. I may be able to deduce the values from external measurements on the HV block. Failing that, data for the trinitron would tell me the voltage range for the H-STAT electrode.
