Well after having come to my last "conclusion" about the cathode resistors I decided to do some reading about biasing in general. I have a RCA recieving tube manual from about 1959 and I downloaded some pages from an earlier version that had detailed info on the 45. WELL as I looked closer and then recalled the pinout diagram that I DID use when I put everything together, one that was on the internet, some kind of tube info page, anyway once I read "pin orientation shown from below" on the RCA tube manual page and then looked at my tubes and then back at the manual then back again then I DID smack myself in the forehead! Yup, you guessed it, I had the plate and cathode switched on the 45s! Well getting that right makes a BIG difference(DUH)!!!! They sound just fine. I did burn up the 1 45 and I think the capacitors on the cathode resistor (100V and I guess with things backwards the B+ was running through them, so now they are all swollen and I suspect bad, I replaced them) But NOW it works! I need to make some more efficient speakers. And I was thinking of a Class A SE with a 6550 in it.
