Testing a Triac (BT136-600E)

I got a couple of the BT136's
**broken link removed**

I was trying to use them in place of a C106B
https://www.mouser.com/ds/2/308/C106-D-108983.pdf
for the Lesson 13 in Electronic Circuits for the Evil Genius (see attached).
Could not get it work, but I don't have a speaker or buzz, just used a LED.
Also tried it with a SCR TYN612 as the book seems to use TRIAC and SCR interchangeably.

Still didn't work.
I found a very basic Triac test circuit.

I've read over the datasheets, but I admit that a lot of the graphs and data is still over my level of comprehension at this point. Am I missing something obvious?

The C106B only needs 0.2mA to activate its gate, the BT136 needs a lot more, maybe 10-20mA.

Your 1k gate resistor needs to be reduced for 12v operation. The Triac test circuit you showed seems ok, with a gate resistor of about 270 ohms. You could even reduce that further to about 100 ohms.
