I thought he was refering to a long and/or heated thread in the past that could have been researched by using the archives. Being interested in the question, I looked up the topic in the archives and found very little.
I too, am interested in adding a 4th valve to my 3 valve compensating euphonium. If anybody has any suggestions, fire away please.
