Would a Mesa Boogie Rect-o-Verb 50 watt combo work for you?
If gives you the portability of a 1x12 combo amp with the dual channels, reverb, etc. -- or stack it on your cabinet for 50w power.
Mine is near-mint (I am the original owner) and it sill has hang tags on it. The amp has never been gigged or played outside of my smoke-free, pet-free home. I bought it as a 50w option when I downsized from my Dual Rectifier solo head and Recto 4x12 cabinets years ago.
