I worked as an operational engineer at Broadcasting House
(RES) in the mid 1980s, straight from university, and spent a couple of very
happy years in Operational Engineering before moving on to work in industrial
electronics. Analogue still reigned supreme then of course, (CDs being but
in their early days of broadcast use) and I became a master at lining up Studer
A62s, B62s, A80s and the wonderfully-performing Telefunken M15As. How I used
to lust for one of those machines at home instead of my measly old Revox!
The continuities and control room, I remember, had a wonderful expensive sort
of smell, of cool air, cable, recording tape and warm electronics, seasoned
with perhaps just a touch of dear old Ray Moore's lingering aftershave! I
can still remember that smell to this day. What a wonderful place to have
worked.
Before joining the BBC, I worked in my late schooldays, and whilst a university
student, on a hospital radio station which was equipped with Spotmaster carts
and those classic Philips mono tape machines - wonderful old transports, a
joy to lace and to edit on. I replaced their old, near-useless, BSR domestic
grams with a pair of ex-BBC RP2/1 units, which were based on the Garrard 301
turntable. These we mounted into the worktop and equipped with Shure SC35s
and some old RP2/7 amps I came across. For many years this set-up did great
service. Once you'd got used to anticipating the half-second or so delay as
the turntable rose, you could drive a fast-moving music show with those, no
problem at all. (The only minor flaw was that if you had the mic open and
an otherwise silent background, the whirr of the "lift" motor was
distinctly audible, despite attempts to "soundproof" the underside
with bitumen-lined plywood boxes!)
As a schoolboy I'd learned a lot by myself by building amps and radios from
stripped down TVs and ex-military junk. This, I was to find, gave me something
of an unexpected edge over my colleagues and contemporaries. Unlike many of
the (fairly young) engineers I worked with, I was very much at home repairing
the older type B valve amps, some of which were, amazingly, still in front-line
use in the control room. I'd often find a selection of the small grey boxes
awaiting me in the morning, left by the previous Night Shift. (This was especially
common following the infamous Generator Test, when brief loss of power in
the wee small hours often seemed to push tottering amps over the edge!). Happiness
was a quiet morning with a couple of these to fix, sustained by a hot cup
of tea and a fresh jam doughnut from Joyce Rose's trolley outside the Control
Room on the 1st floor.
Type D too was often gladly left for me to fix, being of discrete circuitry
and requiring a level of comfort with the (by then) rather old-fashioned germanium
transistor circuits that it used. One time I remember a particularly odd fault
on a stereo D-type module, where the channel balance shifted when the gain
was set high. This turned out to be due to the wrong resistor having been
fitted during manufacture - it must've always been like that, and only got
noticed one day when for the first time in its life the gain got cranked up!
That one took me ages to find, and I don't think the boss believed me when
I did!
Another notorious episode occurred when I was first employed in RES as a summer
student. At that time there were lots of Studer/Revox A710 analogue cassette
decks around the place, which were complex and rather unreliable - not least
I remember because they were often mounted in ill-ventilated cabinets. We
used to check and line these up using a very expensive, bought-in (£100+)
BASF test cassette. One time a particularly stubborn A710 happened to come
my way. The EFR (Engineering Fault Report) log showed it had been worked on
by a whole string of engineers, who for some reason just couldn't find the
cause of the fault -- no playback, just rough, lumpy noise. This eventually
turned out to be because the recording amp had died and was applying a large
DC voltage to the recording head - which, as a result, was erasing anything
and everything inserted into the machine. Nothing wrong with playback at all!
Unfortunately, before this came to light, no less than two of the precious
test cassettes - our entire group's stock - had been tried, and therefore
partly erased, in an attempt to check out the machine's replay side! You can
imagine the wrath of our group manager, who was less than amused by the whole
performance. Luckily for me, the erasures were not my doing, but I was not,
I think, at
all popular with the rest of the RES team for being the one to actually find
the fault and fix it (especially as I was just a student at the time) !
Happy days....
