Looking for triac AC05D

[Tom Servaes]

I'm looking for a NEC AC05D triac to repair our HAKKO 936 variable soldering station. Does anyone have some on hand or know where I could scavenge one?

I'm likely going to order one, but that'll take time.

Thanks,

Tom

Tom, some info via google:

http://www.diyaudio.com/forums/parts/257357-triac-substitute.html -  "Often a resistor in the snubber failing open is the root cause" worth checking if resistors still have their marked values.

Here's that schematic we were looking at: http://dalincom.ru/datasheet/HAKKO_936_schematic.pdf (also attached)

This (https://www.digikey.ca/product-detail/en/ween-semiconductors/BT137-600E127/1740-1028-ND/1154770) looks like a replacement. 

Locally, Jentronics or RAE may have a replacement?
