The TD7 had two turntables and three rotary faders on the front panel. The middle fader was for a microphone to allow the operator to make announcements ~ largely applicable to Bush House, I believe. Unlike later turntables, the stylus was angled, so you couldn’t scrub to locate an in-point. This also reminds me that recordings requiring more than one disc often had alternating tracking, so that the first disc would play from the outside in, then the second would play from the inside ~ this enabled less noticeable changeovers as the quality of recordings deteriorated towards the centre of the disc, where the stylus to groove velocity reduced with decreasing radius. For continuous material, mainly music, there was usually a significant overlap between discs, to allow the operator to sync the succeeding disc with the one currently on air and I remember practising changeovers at Wood Norton, but I never had to do it in earnest.

Here's a TD7, it tracked at 2.5oz. If you're talking of the 1960s I don't believe there were ever any at TV Centre.

'Grams' at TVC were twin units called RP2s and were Garrard 301 tuntables with fast start facilities. They had Tannoy variable reluctance cartridges which 'turned over' to give a choice of fine or coarse groove stylii.

The last TD7s in West London Television were at Lime Grove Studios D,E, G, and R and were replced just as I started on Grams (just as well really).

Hi Alec  

 

It was a BBC TD7

 

In my earlier radio studio testing duties we were told the method of setting the tone arm was to place the needle on you finger - increase the weight till it drew blood and take it back a notch. Happy days

Hi,

What were the old heavy cumbersome record decks in the TC studios Sound 
Galleries in the mid 1960s?  I think they had moving coil pickups (they 
were heavy) and had straight arms: mainly ran at 78 rpm IIRC..

Even better, if you have a picture of one, that would be magic (it's for 
a U3A talk/presentation).

I have had a troll round the internet and the Tech Ops archives, without 
success as yet.

Thanks in advance!
