I just checked the digi-key website. Thats the thyristor for sure. I double checked and was d not 0 after 169. The glass diode is burnt looking but it seems theDigi-Key has the parts
bt169 thyristor = Digi-Key part number 568-8264-ND
12ohm 1/4 watt resister = Digi-Key part number gkCF14JT12R0CT-ND
thyristor burnt to. Maybe that why can see the numbers on the glass diode.
