  > Russ: Thanks for your reply. I hooked another transformer in circuit -
  primary reads 175 ohms, secondary .7 ohms. Speaker doesn't give good sound
  as you said. Bad transf. is about 3 times larger than the one I subbed for
  and iron core is much larger in the bad transf. Any ideas? Thanks
  again. Kenny
