Dynaco Pat-4 resistor ratings

[eizner23]

Are all the resistors in this unit 1/4 watt, other than the 3w resistor noted in the pat-4 assembly manual? The manual doesn't note ratings.

1/2 watt would be fine. Even if a few are 1/4 watt.

All of the original resistors were carbon composition resistors rated at 1/2 watt. Any resistor on the PCB's could be replaced by 1/4W metal film, with the exception of R20's, the big 620 Ohm collector resistors. There are also a few exceptions in the power supply Here's the parts list fo the PCB's (mostly):
