It is too bad that someone doesn't make a guitar oriented mono tube power amp with two 6L6's that is about 40 to 50 watts with a half power switch. That would be a great rig for gigging. I am saving up for an sms and I am having a hard time figuring out what power amp to get. I am all about the Mesa Boogie 50/50 but it would be super heavy and be way too much power for me (2 50 watt channels), I just want one 50 watt channel. the 17 watt power switch would be great on that for smaller gigs, and honestly, I would probably use that more of the time. I am a 1x12 guy, I don't have any need for two 12's. I am loud enough for 90 percent of my gigs with the Fender Deluxe Reverb Reissue with a JBL E120 in it, but want to upgrade and have a more versatile rig with more headroom.
I don't think I want to get a McIntosh because of price, and I want something that will be super reliable and lighter weight. the mc 50 would work out OK if it was in great shape and I could trust it, but something that old is bound to have issues at some point. There are actually a nice pair of them on ebay right now, a little pricey, though.

It is really tempting to go with a MosValve 962 or Rocktron 300, but I have never tried either one of these, and don't know how they would sound in comparison to tube circuitry. I have time to figure it out, because I don't have the money right now, anyway. A head version of any fender with the AB760 circuit in the pre and a 40 or 50 watt power section would be cool, too, although probably not quite as awesome as the sms ctp with the jerry mod and a mesa 50/50. I have been really happy with the Fender DRRI, though, just need a little more headroom.
