Question SAC187 pinout

Could someone please give me a pinout of a SAC187 triac? I received this from Peavey as a replacement part for an M-2600 Mark V amp that would not shut off. The bad triac looked like a full wave rectifier with only 3 pins. The replacement is a TO-220 case. I have requested info from Peavey, so far nothing. I have scoured the internet looking for a datasheet or pinout. So far nothing. I BELIEVE pins 1 and 2 are the main terminals, and pin 3 is the gate. ??? Any help will be very appreciated.

Most likely, but to make sure, here's a test method:

This is from the original service catalog of Peavey:

1) Original in-house part number: SAC187
2) Field replacement number: 2N6346A

Due to unavailabillity of 2N6346A, we replace with success the SAC187 with BTA16-700B for many years in authorized Peavey service stations. The pinout is same with SAC187 and is from the left to the right:
pin1= A1
pin2= A2
pin3= Gate
