Subject:= LF: 40 years (completely OT, but...)


40 Years ago today decima= l money was introduced to the UK =A0It was half term
hols, and at the age of 12 I went into one of the electronics shops in Hur= st
St, Birmingham (a bit like London's Edgware Rd. back then) =A0to= buy two
IN4007 diodes as I needed to make a PSU for some valve project= . =A0 Being
my first purchase with =A0the new money I remember exactly how much those= two
diodes cost : =A0 The two diodes were 50 new pence, (which probabl= y sounded a
lot less than ten shillings they were the day before)
Consulting an RPI chart shows about 1100% inflation since Feb 1971 which=
makes those two diodes something like =A35.50 at today's prices.
Th= e current cost from Farnell for the IN4007 is about 8p, including VAT, for=
two-off.

Now, =A0even allowing for the fact a local electronics= shop =A0would have a
massive mark up on components, the price from a catalogue supplier wouldstill have been in the =A015 - 20p (=A31.50 =A0- =A32 now) region.
Were electronic components really so much more expensive back then - it<= br>wasn't an exotic diode.

Completely OT, and nothing whatosover to do with LF, =A0but about the= only bit
of component pricing I really recall accurately from those da= ys.
