Mike,

I collected 4 spare IRF250 power Mosfets for the Decca TX from the Crawley
Club at the meeting last night and will stick them in the post to you
soonest. I was unable however to find among the remaining bits and pieces
one of the protective MOV devices but similar ones are available from RS or
Farnell distributors
