40-145 speaker issue
#18

Well,
I got the speaker from Mike but NOTHING! I put it in just like the old one and it fit perfectly. It has the same numbers on the cone but different nimbers on the metal. Tried putting the screw driver on pin 6 of the 7B5 and got no hum. The screw driver did clip and I got a good buzz, Icon_rolleyes

When we tested it with another speaker it worked so I dont get it. I cant have 2 bad speakers in a row right? At one point I put the volume real low and I got some music but that was it. I hooked up the antenna and then tried it without it. Tried all buttons, checked the connections checked the tubes, checked out! I am about ready to throw it, Icon_twisted
Any ideas?
