Hi All
Sorry I didn't chime in sooner, I just saw this post this morning.
I'm pretty rusty on this, it's been years since I modified my 70's (3) to AVC.
Let's see: I used a 1N34 for the detector, removed the grounds from the IF and RF tube signal grids and ran them back to the 1N34 through a 2.2 meg, removed the original dual volume control and installed a 350K pot. for audio control and detector load. Converted the original 24 detector stage to a audio amp.
The audio fidelity is excellent. The RF gain is excellent. The "Plate detector" distortion is gone, which is the reason I did all this.
If you need the schematic, email me and I'll send it to you.
