Saw this on eBay:
Ex BBC Studio Talkback Microphone / Mic / Base Amp unit
Old BBC studio talkback unit, it came out of an OB truck and is 125 Volt so i have not been able to test it. Sold AS-IS
Please take a look at the other BBC nick nacks that will be going on over the next few days.
Fell of the back of an (OB) truck, eh? Seems like she has a lot of other BBC equipment up for sale too.
