Someone correct me if I am wrong, but standard policy for amps is usually that all resistors are 1/4w unless otherwise specified. Not surprising that modern resistors are going to be smaller than the ones in a vintage amp. Plenty of resistors, particularly in the power filtering section will specify a wattage rating. Be sure to check the value of the resistors you are replacing with your meter if your not clear on reading schematics and resistor color codes. It can be easy to mis-read a resistor, and colors can be weird even one batch/brand to another, let alone read backwards if you aren't paying full attention etc.
