Input Stage Resistors.

Hello Mark,Thank you for your reply.
My next question concerns the front end resistors as shown in the manual schematic.Some are shown drawn with a thicker line but no wattage value is specified.The 45K resisitors are obviously shown as being 5W as they have to drop quite a bit of voltage.My manual also does not show a 600 ohm resistor in between pin 2 of V3,the plate and pin 6 of V3,the second sections cathode.Should this resistor be there or was it deleted later.
My next question is very similar to the first I posed.Everyone seems to show plus and minus 300volts for the front end supply yet the manual shows +325 -325 ~25v.I imagine that this is not too critical although if you wanted to add a FET type CCS and a voltage strap you might have to re-calculate a few values.
