Hi all,

I've been trawling through my various catalogues tonight looking for
toroids that might be suitable to wind hi-Q inductors around, but am
disappointed to see that all the stuff on offer seems to be geared
around interference suppression and is consequently - I assume - very
lossy material. Does anyone know of a source in the UK that can supply
small, *low-loss* toroids by the dozen to the hobbyist via mail order?
