Thank you. The 1215 combo was the biggest surprise. There's a local rehearsal set up that has an old beaten up 410 TE combo in one of its rooms. It was plugging into that with extremely low expectations that convinced me I had to have an AH150/200 head; the combo being just too big and heavy. The first I found was the rack mounting AH200 then the Mk5 AH150. All good, no more TE heads needed. The next visit to this rehearsal set up we were in a different room that had a beaten up 1215 in it. Plugged in and what do you know, that beautiful Trace Elliot oomph coming from something much smaller and lighter than the 410. Around the same time an as new example popped up on here which I was lucky enough to acquire. The AH100 (or 130, I cant tell which?) was from a local guy who didn't gig so once again too good to pass by. That's definitely the last purchase (yeah, right) unless a mint SMX250 surfaces somewhere convenient.
