I ran my 120 wt XXX combo with 2 PT's, it still weighed a metric ton so no big difference at that point. I don't hate the XXX speaker, I just think it reacts much like a V30 in a lot of ways, at least what I don't like about V30. I find it more appealing in a mix rather than on it's own which is how it'll get used. I used the head with a 412MS cab which tamed some of the top end edginess.
I swapped V1 and 3 for JJ's and used a gold GT 12AT7 in V2. Amp sounds great, super happy with it.
I also got the footswitch working properly. I cleaned the cable ends and jacks again and it works perfectly now. This amp sat in a basement for a while and while it was in great shape it definitely needed a good cleaning. All worth it though, it cost me $400 which really seems to me to be a great deal for a 3 channel MIA combo.
