Hi Daniele,
If you really want to do the works on salt water caps, by all means, but a
simple 'bucket cap' is much better and is also for free. Use something like
used mayonaise or likewise 10 liter containers. They are made from
Polypropyleen and are 1.3mm thick. Search the archives for 'bucket cap'.
There is one advantage in using salt water caps: they have a natural
resistance against current flow and therefore protect you from killing the
tranformer (or you).
I should definitely NOT start with a matched cap! You don't need it for a
running TC and when it is working you can always improve. (Not to mention
the filter and safety cap that will absolutely be necessary with a matched
cap if you don't want to fry the transformer)
