Steve tells us that this great looking vacuum tube amplifier project was inspired by the Spare Time Gizmo single-ended 6T9 tube amp kit from 2004. The circuit ideas for the push-pull output stage came from his EICO HF-81 and RCA Receiving Tube Manual. The preamp stage uses 12AX7A tubes.
All of the connections are point-to-point. For the enclosure, the combination wood and brass chassis consists of a small sheet of brass and Poplar wood. The brass sheet was polished to a shine and the Poplar wood stained with Minwax Red Mahogany stain and finished with an Amber Shellac.
Steve is very impressed with the performance of this tube amp. He notes that there is plenty of gain and a nice rich sound.

Great work Steve!
