Default Re: Beware!

I wonder what the subtle code differences indicate between ours. I have a NOS box of 250 with a stock code and date stamp of June 1984. I will have to keep an eye on them as whenever I replace the mains filter I put one of these in it's place, I feel a nervous twitch coming on

Glad you got to it before anything happened.
