Amplifier and Tube Satisfaction Survey

Finding the right tube amplifier, as well as the right tubes, was an expensive and time-consuming process for me. I'd like to save others engaged in that search time and money by gathering information on what tube amp owners currently use. I'll start by surveying owners of two popular tube amplifiers and expand the survey if the results are found helpful.

You, too, can help to make it easier for those entering the journey. If you are the owner of a BoyuuRange A50 or Willsenton R8 amplifier, please share which tubes work best in your amp. If you have both amplifiers, complete two surveys so that the tubes used in each amp you own can be identified. 

I hope the data collected can help answer questions such as:

1) What percentage of respondents feel their BoyuuRange A50 or Willsenton R8 is magical, exceptional, or just acceptable?

2) Of those that feel a certain way, what tubes do they use and what do they think about each type of tube used?

You will see cumulative answers after completing the survey.
