See I guess that’s where I was getting confused.. I thought a TPF was like a OPF except in two pieces?? Lol and a tube and plate was something completely different. I have the chance to buy a MB3 from Frank Neats shop and have him convert. I was just doing some research to see if this was something I really need to make happen. The only information I have right now is that it is a MB3 with the original 40 hole arch top tone ring.
