Decode of service numbers - UK Vintage Radio Repair and Restoration Discussion Forum

Hi Folks, I have a pair of very nice 3 terminal chokes (appears to be a centre tap) that are labelled 10C/16950 AC4261.
They are housed in a grey metal can rather like the big paper Mil caps.

Can anyone decode this and tell me what they are. Looks as if they could be useful for a valve PSU I'm building.

Thanks, Ed

Hi Ed,

Hi Ed,

No problem, A.P.1086 Section 10C tells me that your item is 'Chokes, LF, Type 721', with two coils, each 4.5H rated at 90mA.
