    If your planning to do this overseas in Europe or the UK, one really important point is to make sure that the transformer you want to use was designed to be used at both 50Hz & 60Hz!

    Anyone experiment using other SiC Varistors? I've seen some lower voltage variants sold on ebay (supposedly USSR stock).

    No thats fair. Really, my example was more relevant to C26. But Im a bit of a compliance dink, and best practice is caps on or across main lines voltage should be safety rated class X.

    I would definitely go mainframe, if I came across a 7104 in great shape (at a great price). It would be cool to own the piece of gear that reached the analog/1GHz benchmark.
