Transformer Disclaimer
Regarding the transformer output ratings, I need to clarify how to interpret them. I use the manufacturer’s specifications in the description of various builds, but I don’t guarantee that you actually get that output in every instance.
For example, a 6V6GT in a single ended amp will only have an output of 5.5 watts regardless of the output transformer used. An 8 or 12 watt transformer will give you more headroom and a bump in volume over a 5 watt unit, but it’ll never exceed the ability of the tube itself. When you get into the push-pull circuits like the 5E3, then the output of the two 6V6GTs can go up accordingly with some of the larger output transformers.
Please keep that in mind when looking over the amps and feel free to ask questions if you need to.
