Default Help with R values

Does anyone have simulator software in which to check the R values for Joel's preamp? I am trying to use a power supply voltage of 245volts. I have checked all connections, parts placement, and so forth. Nothing is missing or misplaced. I don't have the formulas in which to check the calculations myself. I just can't seem to get the correct voltages/bias on the tubes. When I do it doesn't seem to have any gain at all. Any help would be appreciated.
