Ok
I think I stand corrected.
I think the output transformer is ok. On the primary side i have 450 and on the secondary side I have 0.3.
I was expecting that the field coil was installed and working when it was not.
So, that brings two questions.
1) Can I put my old single end transformer on the new speaker? Remove the push pull transformer and install the single ended one? I think the voice and field coils are the same. Hence i think i can swap the transformer and be happy.
2) The main unit needs to be gone thru. No ifs and or buts. Re cap. New resistors. Check tubes etc. But my question is, what causes these field coils to burn out or go open? Would it be bad filter caps? A bad tube? A short to ground? Something caused the field coil to go open on this unit. Need to be on guard and make sure it gets resolved.
Cheers and Thanks Kindly!!
