Ekco AC18 HT Unit - using?

[Terry]

... Usually now written as 4uF where the u should be a greek "mu" but I'm too lazy to dig out the symbol ...

Tut tut, Jeffrey!

I have little text file which is always open for anything I want and, if the symbol isn't there, I make a point of looking it up and adding it for future use.

The 'mu' symbol is µ and another common one is omega: Ω
