Hey guys, I just ordered a new Purity preamp. I had the black metal knobs and JJ Tesla tubes installed. I can't wait to get it. If anyone has anymore opinions or advise on this preamp, let me hear it. I still have an SWR Workingmans 4x10 for sale by the way. The wait time is supposed to be 5 weeks or sooner. We'll see. I am in GAS hell!
