replace 47-1230 power transfomer
#1

I ordered a replacement transformer from radiodaze, but Im a little confused on the voltage levels and how it relates to the new transformers. They didnt have a direct replacement so they sized up 2 transfomers. One has 6.3v , 5v ,104ma and 550vCT taps the other smaller one just has 6.3v tap rated at 1a. On the schematic the voltages are listed at 310v ,-16v and 240v. I dont how to correlate these voltages with the new transformers. Need some help wiring it up , Thanks

You'll definitely need the larger one. But someone might have an original spare, (I do not.) Try posting as wanted item on this forum, you never know.

I think where the shaft comes out of the brass piece, there should be a clip.morzh — 06:47 PM
