You can convert the 200CD to 240 volt operation by changing the transformer primaries from parallel to series as described in the manual. The -172 volts at R40 is a little higher than the -155 quoted in the manual but that shouldn't make much difference to its operation. At -172V the power dissipated in R30/31 works out at about 10 watts each if they are 3100 ohms so they need to be rated appropriately.?
