This amp is a version of Grant Wills ultralinear PP amp based on 12AX7 preamp and driver stages driving pairs of PL36 line output TV valves and using 100V line PA transformers, a budget priced amplifier concept! I modified it to use the equally low budget Russian valves 6N2P drivers and 6P7S output pairs. It was my first valve amp build (I was always more of a microprocessor circuit constructor in the past!) and it took me six months sourcing the parts and the drilling, filing, sanding and other mechanical details that are so time consuming with a valve amplifier, but I am very happy with the result. It's in daily use and I love the sound of it!Click the image to open in full size.

Thank you for the nice comments...
Funny you mention the Spirit of St. Louis, as "Slim" was related to my grandmother.
I have always liked the jeweled finish on my metal projects.
