just did a recap of a Silvertone for a cousin - I used two 100uf 250V caps in parallel for the 160uF input filter.. I used radial caps, stacked. it was a tight fit in the can, but worked great. The B+ went up only 4V over the Sams value, so it worked fine.
Most caps were rated at +80%, -20% tolerance, so there was a wide variance of value. Todays caps are more tightly rated, with +/- 20% tolerance - that's the "M" code on most electrolytics. So your 150 could have been as high as 260-270uf new, hence the 200uf will suffice just fine.
Only in series do you need balancing/sharing resistors.
