Default Re: Levell TM14 Modern Equivalent?

Hi!

Quite apart from the fact that a four-year-old could make a far neater and clearer effort than whoever draw most of Levell's circuit diagrams for all their gear, the two main issues with these are failure of the two BC184L multivibrator transistors and short-circuited turns in the secondary winding.

Do check that none of the winding leadouts have broken away from the bobbin - if any have you'll need to have a chat with Ed Dinning!
