Hello friends!!! Happy new year!!!
Back in action after a long time...
After replacing 7B7 tube, noise heard but not music
So i started checking DC values... results was not good, but restored. Still no reception... "digging" continued and found something interesting...
This is an accurate schematic i've found (an old Ron Ramirez's reply) although it is for a different model. The tubes are different but the components values and positions are the same. But...
...Z1 transformer seem to have (at the schematic) 5 active pins (1, 3, 4, 5 & 6) although at the radio are only 4 (1, 3, 4 & 6). So pin #4 of 7B7 tube seem to have ...nowhere to connect. Furthermore, this tiny, white component with the red line in the middle, i have no idea what might be...
Thank you in advance!!!
