Pilot 240 power supply - Duncan Amps software use help, please !

Pilot 240 with Simpli matic test panel; Schematic needed , proven mods ? Grid stop resistor identification.

I am in need of a schematic for a Pilot 240 with the "simpli matic test panel", serial # 267178 . I have an earlier Sams Photofact dated 1960, and note the cathode bias set up and resistor values are different between the two, as suspect other differences, hence my request. Also, any suggestions for responsible & effective modifications to safely improve fidelity without shorting tube life ? I am going to replace all caps, bias resistors, and power supply resistors; as such this would be the perfect time to change key component values to optimize performance. Thanks in advance for reply ?. Also, grid stop resistors for output tubes; I have read I should repalce them all with metal films - Are these all the 270K resistors that connect to el84 pin # 1-2 ? Thanks in advance - Steve
