Hi, Excellent, well done, have fun
R1, R4 and R5 will all actually be dissipating less than a 1/4W each so 2W will be fine power-wise.
2W and 3W metal oxide have the same voltage rating and are the most robust of the film types.
The circuit shows R1 as 2W and R4 as 1W. I donít know what yours was actually built with, but the 2W MO should sort the problem
