   Ermm.  It's a stereo amp so 2 x 100 x 10shillings is   
   100 QUID. Actually the price was UKP 112, which   
   in those days was a month's salary (gross) for most   
   of us.   
      
   At the rate of 10 shillings/Watt, my small rented   
   apartment in London at that time cost me 6W.   
      
   Radford was one of the few companies that did   
   boards assembly, wiring, chassis fabrication,   
   paintshop and in particular transformer winding   
   "in-house", .  Without having to use sub-contractors   
   and middle-men they could build more economically.

   Why a couple?  It's a stereo amplfier.

   The THD at 100W was 0.1% which, at typical   
   domestic listening levels, was probably reduced by   
   an order of magnitude.   
      
   The STA100 that I have was built in 1966   
   It still has its BBC part number and revision   
   stickers on it.. I acquired it in perfect working   
   order in1987. It has been well maintained, and   
   still performs flawlessly, forty five years later.   
      
   I wonder how many of the users you refer to could   
   make modifications to improve either performance   
   or reliablilty?   
      
   >Who really needed to buy a Radford in 1967?   
      
   Well broadcasters and professional studios   
   had them in quantity.   
      
   Radford had a range of lower powered amplifiers   
   the STA15 and STA 25 for high end domestic use.   
   The latter was often seen in studio listening rooms also.   
      
   There were also mono versions of these amps, MA15   
   and MA25
