Work slowed down my effort this week but here is my next step. I am going to plug the following amps into the BJ cabinet tonight. This is to get an idea of how the single 12 inch speaker in the small cabinet responds. Fortunately I have the following amps at my disposal.
I want to get an idea of what exactly tonally I might be stepping into by the various tube sets. If the honking midrange tone of the BJ does not change all that much, I may move off this conversion. If I hear something I like, I will probably mod in that direction.
