Because I am slightly mad, I am modifying a valve portable radio to have an extra FM waveband. I have picked up some DC96 for the front end oscillator and the data from Valvo on radiomuseum.org provides a schematic with transformer winding specifications.

I'm having trouble with the translation of these instructions, as terms like Cu SS, and Cu vers. mean nothing to google![:)](http://saba-forum.dl2jas.com/wcf/images/smilies/smile.png)
Also I'm not sure if the intention is for tightly or loosely coupled windings (I guessed tight for the oscillator and loose for the pre-select transformer)
I wondered if some-one here skilled in the art and a native speaker could help. I have had a go but the tube won't oscillate..
