I dunno what the T13 pill looks like (don’t have one), but this host has intrigued me as an MT-G2 option ever since I did the T08 (it has since been rebuilt with a DRY driver and Noctigon).
I expect the T13 would be an easier mod than the T08 because the cells are already serial.
If someone that has a T13 can take a pic of the pill and emitter end of the reflector, it will help determine this viability. I suppose there is a review somewhere with pics already but that search button is all the way up there…
