Default Bush PB12

Hi Folks

Recently got hold of this set, and what a huge set this is and heavy too. The case was falling apart both ends when I unpacked it and I was not surprised at the amount of dust, the smoothing cap is an odd value 32uf and 16uf so in this case I can't put a 32+32 I will have to re-stuff the original, not sure of the rest of it though, bit more investigation work, there is a 2uf electrolytic underneath and I cannot find anything in my capacitors to match it so I am now wondering what I can use. Here are some pictures of it so far.

According to the schematic I can't see why not.

Replacement for the 2 uF (Eg):

The 2uf 350v capacitor can be replaced with a 2.2uf 400v though in that position it is not critical, and can be stuffed into original can if required.
