There’s a pill that you can back out of the head. The MCPCB is a bit tricky because of how it’s soldered. Some pics here: What did you mod today? - #9110 by gchart
Sidenote, the mcpcb of my brass Pineapple has a different shape than my Ti Lan, which is smaller and even more tricky
Thank is Gchart and Yokiamy.
Those pisture look exactly like the e03 pill and mcpcb I just did a swap on. I went in through the bezel And head, removing the reflector. I unsoldered that small mcpcb and reflowed with my hot plate. My mcpcb looked darker then yours when I was done as I messed up the orientation of the emitter, a couple of times. Still learning 
Thanks for the info !
Yokiamy- do you recall if the mcpcb on your brass was smaller than 14mm?
Im not exactly sure which one, (i think my Ti Lan)
but one of them was square and sat on a copper pill where the square mcpcb exactly fits in the square slot.
Edit, this is my Pineapple
Awesome, thank you for the info!
