BY187 01 diode with an 820 ohm carbon resistor.
Thorn EMI Ferguson ltd service division.
Replacement diode T.E.F part number 00E9-016-002
I think the combinator is for a vintage TV repair.
From the Philips TV factory that was in Croydon, London.

I think the resistor is around 1/2 watt.

Please check my other item.

Lots of Philips Mullard there.
