The TB47 capsule was one of the better Chinese copies, a centre electrode type and the sound from the mic was silky in the extreme. It’s a really chunky microphone with a sturdy power supply with its variable pattern switch.
I still have a TB47 and use it as my favourite vocal mic (into a TDC of course!)
Talking of the TDC, it is taking some time to get the manufacturing of the new ‘voice channel’ organised, but the development is complete and it is ready to go.
Please have a little more patience and I will announce it as soon as I have some stock.
