[Collins] mmf and uf

[Chris Pedder]

Hi,

Over the past few days, and I haven't been watching as carefully as I 
should, there has been reference to mmf and this has been equated, from 
time to time, to pf.

This is incorrect both logically and historically. When I was in short 
pants, I seem to recall that mmf was the common designation for what we now 
refer to as uf. (milli-milli being the equivalent of micro) This is a long 
time ago and my memory may be less good with advancing years.

My absolute first memories of life consist of being made to sit at the 
dining room table and insert 'T' and 'U' transformer laminations into a 
bobbin, alternating sides. These transformers were used in homebrew TV sets 
just after WW2. Slave labour for my wicked Dad   :)
