The caps in the 45 are used to lessen the high frequency response to the amp. Values are not particularly critical just the larger the capacitance the less high frequency response. I generally error towards the smaller values. Make the sound brighter rather that muffled. The 45 also has what is called loudness control (it done via the tap on the volume control) which lessens the bass response has the volume is increased.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
