Here's a pic of my Stephenson 30 watt combo. These are made by Mark Stephenson in BC, Canada.
The amp has a very flexible output tube switching capability which gives the capability of running the 4 output tubes (2 x 6V6 and 2 xEL84) in any combination including single ended mode. It also has Power Scaling which I have found to be a great way to get a cranked sound at more reasonable volumes.
Please ignore the "non-Hamer" guitar in the photo
