Hi MrFixr55
I have read the rules and will abide by them
The problems I have is with the detector amplifier (sorry not the first audio) The first audio has the correct voltages.
The audio is clean and undistorted at the grid of the detector amplifier but distorted at the anode. I have replaced the tubes, the 27’s, both the detector rectifier and detector amp (twice with known good tubes) to no avail.
The detector rectifier has negative voltages on the plate where the schematic shows it should be at zero volts.
Hope this explains it better.
Regards
Roy
