Interesting. Does the amp allow use of a 12 volt tube in a 6 volt spot (switchable?). I use the same noval to octal adapters on my Encore, but at the same voltage spec. 12SL7 slot, 12AT7.
So fun fact, the 12A_7 family for the most part works at both 6 volts and 12 volts, you can see is this data sheet both 6.3 volts and 12.6 volts are supported: https://www.jj-electronic.com/images/stories/product/preamplifying_tubes/pdf/ecc81.pdf
Not all 12 volt tubes support this, for example the 12SL7 will not work in a 6SL7 slot based on my tests (in my tube tester), and I suspect the data sheet supports that as well. In the Mogwai SE/Bigger Ben I have found the 5751, 12AT7 and 12AX7 sound quite good and as their data sheet suggest support 12 and 6 volts.
