Hp 70000 system ->> Hp 70206a Mono Display R1-C1-S2 values

[croma641]

I'm evaluating (= deciding whether to repair) a Hp 70000 system (severely damaged);
I'm looking for the AC main filter diagram of the Hp display Hp 70206a (destroyed/melted).
Can someone send me the schematic or the values of R1, C1 and S2?
Thanks in advance
